10 Best Indoor Hygrometer To Measure Humidity In 2022 – Complete Guide

Today's Gardener ( participates in the Amazon Services LLC Associates Program.

We all know the importance of maintaining proper conditions for our plants and making sure they have the ideal environment. That’s why you need to pay special attention when selecting the best hygrometer for your home.

What exactly is a hygrometer? A device that helps track both temperature and humidity. That’s why you need to know what is it and how it works, if you need to maintain the correct room temperature and humidity.

If you want to learn more about and learn how to find the most accurate hygrometer for home use, this is the place for you. I’ve prepared an insightful guide with 10 highly ranked accurate hygrometers, so all of you can find something suitable.

What is Hygrometer?

Also known as a humidity meter/gauge, this is a gadget that measures humidity in the air. By calculating temperature and pressure changes, this device delivers information on the amount of moisture in particular surroundings. In other words, it is perfect for testing moisture in plants and their environment.

Once you start exploring, you will discover versatile types of gauges:

Types of hygrometer gauges

  • Digital
  • Electrical
  • Mechanical
  • Psychrometers
  • Dew point

Digital devices are often utilized in industrial facilities, greenhouses, and other outdoor spaces. That’s because they give instant and precise measures. They are quite simple to use, and you usually get an instruction manual that will tell you how to set it up well.

Some models come with additional functions and features. For example, you can preset the measures you need, and if they are higher or lower, the app will let you know that the adjustment is required. Then, some of them feature tiny faces (with sad or happy expressions), which would indicate whether the conditions are good or not.

On the other hand, mechanical ones use an organic substance that reacts to humidity changes. It enlarges or shrinks, which causes the needle to move, measuring the moisture level in the air.

A psychrometer is quite an unusual gadget. It uses two thermometers-one with a dry and one with a wet bulb. Humidity activates evaporation in the wet bulb, and as a result, the temp is lower. The difference in temp. between these bulbs represents humidity.

Dew point features a polished metal surface. As humidity goes up, moisture condenses on the surface, which is used to measure the current level. They are the most precise of all.

My main focus here will be digital ones, so without further ado, here comes the list!

ThermoPro TP50 Digital Hygrometer

Multipurpose Hygrometer with a Large Screen

One of the first things that draw the attention here is the large screen and huge digits, thanks to which you get clearly displayed information. With a convenient indicator that tells whether the room is dry, wet, or comfortable, you will be able to react on time and adjust the conditions.

Data are updated every 10 seconds, so you can track the most recent changes. It can be used in greenhouses, but it works fine as a thermometer for reptiles, soli, cigars, freezers, refrigerators, and many other uses.

Another great property of this gadget is that it features a selector that allows you to switch from Fahrenheit to Celsius and vice versa. It is powered by one AAA battery which comes with the product. Also, there are multiple options to attach it- it has a magnetic side and tabletop stand.

A couple of users agrees that this one doesn’t give the most precise measures for humidity. It’s lower than you measure it with any other well-calibrated device. But once you get used to this discrepancy, it won’t bother you a lot.

What we like
  • Large digits for easier reading
  • Pocket-sized model
  • Switch from °F to °C and vice versa
What we don’t like
  • Not the most accurate model

Govee Smart Hygrometer Thermometer

Govee Smart Hygrometer Thermometer

Accurate Hygrometer for Home

Having a built-in Swiss-made smart sensor, this product provides precise measures. For temp. it’s about ±0.5°F while humidity is ±3%RH. The device has a range of around 80m/260ft, allowing you to check data remotely. While it covers the entire home without problems, do keep the range in mind if you plan to put it elsewhere (for chicken brooders, for example).

Speaking of location, the gadget comes with both a hanging hole and a small stand, so you can either put it on a table or some other surface or hang it. Due to its small size, it’s not difficult to shift position whenever you want or carry it to some other places to measure temp. or humidity (cellar, basement, greenhouse, etc.)

Thanks to the convenient app, you will be alerted when any of the data (either temperature or humidity) are not in line with the preset range. In addition to this, you have an insight into records from the previous 20 days, which will help you monitor all the changes and react on time if adjustments are needed. But that’s not all- even data from the latest 2 years are available, and exportable to CSV format at any time.

Do keep in mind that it’s necessary to calibrate the product before you start using it. You can rely on a gadget you already have for the most accurate settings. Also, some users noticed lagging, approximately 20 minutes. So, chances are the temperature you see on a display is the one from twenty minutes ago.

What we like
  • Precise product
  • Large LCD screen
  • Smart app alert
  • Easy to connect
What we don’t like
  • Small lags in reporting average temperature

Govee Smart Temperature Humidity Monitor

Different Applications of Hygrometers

Why do you need a humidity gauge for? Is it for your plants or incubators? Or perhaps you want a reliable gadget for your cigar humidor? The answers to these questions will help you decide which one fits your needs.

Allow me to introduce you to the most common applications for digital humidity meters.

Hygrometer Best Home Use

Depending on the size of your home, you’ll need one or two gadgets, which will give you insights into overall conditions. Some models work on Bluetooth, the others use WiFi. For this purpose, you won’t have to bother a lot looking for the most accurate hygrometer there is.

Of course, if you are a proud owner or some super sensitive plants, which need extreme conditions (too low or too high humidity), then you need a bit more precise gadget. On the other hand, if your main concern is outdoor humidity, then a home weather station will be more suitable.

Hygrometer for Best Greenhouse Conditions

Regular monitoring of conditions in the greenhouse is the only way to provide optimal conditions for your plants’ development. What you need to know is that there are no universal and ideal humidity levels for greenhouses in general.

So many factors impact that- different seasons or times of the day, your location, types of plants you have inside, and so on. For this purpose, you’d have to be extra careful when selecting the gauge, so to eliminate any dramatic changes in the conditions.

Cigar Humidors

Keeping cigars in an adequately humid environment is the only way to preserve their flavor and taste. So, even if you already have a solid humidity meter for your home, you’d need to buy a separate one for this.

Mind the size of the humidor when selecting. If you want to monitor the conditions remotely, then a digital instrument with an app is what you should be looking for.

Instrument Cases

If you own a musical instrument, then you are probably aware of how sensitive they are. Having in mind that they represent a significant investment, you need to monitor humidity. Even when your instrument is in the case, it can suffer from inadequate humidity levels. So, to avoid warping, cracking, shrinkage, or other issues caused by too low or too high humidity, get a gauge.

In addition to these, you can also use it in a terrarium, incubators, wine cellars, saunas, and any other room where you need to be familiar with the moisture level in the air. Consider it a smart investment, as it has multiple applications. Just make sure it’s the one that fits the purpose.

What to Take into Account When Looking for Best Hygrometer?  

Before the shopping time for the best home hygrometer comes, make sure you are familiar with all the properties and possibilities of this gadget so that you can pick the right one for yourself. Application aside, there are a couple of factors that you need to analyze before purchasing, such as:


No need to go into lengthy discussions here, it’s quite obvious why accuracy plays such an important role in picking the best hygrometer. To be absolutely sure how precise the device is, find its ±% RH rating. This represents the margin of error that the sensor has. The best would be if it’s ±1% RH, but anything up to ±4% RH is still okay for the majority of applications.


If you opt for a mechanical one, then this one is not one of the concerns. But assuming that you are looking for a digital one, check how it connects. If a model uses Bluetooth, but it has an app, you’ll need WiFi to be able to use it.

Power Source and Battery Life

The devices I described here are wireless, they don’t need to be plugged in. But in case you need one like that, check the length of a cable. If it uses batteries, see what type is needed and how long do they last.

Remote Monitoring

One of the greatest benefits of modern-day gadgets is the option to monitor the conditions remotely. And not just that, but receive alerts if they are not in line with your presets.

Even though they are slightly pricier than those without these assets, it’s still not a waste of money. This especially goes if you have multiple rooms where you monitor humidity. You won’t have to walk all over the place to see the measures.

If you opt for one of those, here’s what you should check- is it possible to customize the alerts? How often does the gadget measure and send reports? These may seem insignificant, but they will help you determine precisely what sort of gadget is compatible with your needs and requirements.

Additional Support for Sensor

In case your place is large or you need to supervise multiple locations at the same time, then you need a gadget that can connect several sensors to the one system. How many rooms do you need it for, is the question you should answer. Do bear in mind that devices themselves have a limited range, so you’ll need to make a smart plan to position them well.

NIST Certification

This is a nationally recognized calibration standard, which indicates whether a device is in line with ISO and other requirements.

User Interface

How difficult is it to read all the data? Are the digits large and clear enough? Is the screen backlit, or you’ll have troubles reading when the light is lower? Once you analyze all these, you’ll know whether a gadget is a user-friendly one or not.

Data Logging and Storage

As you can assume, mechanical gauges don’t have this option. If you need a historical report of the levels over a longer period, then you need a digital one that can log unlimited data. Some devices store a limited amount of data, up to 24 hours, while the others can deliver reports for up to 2 years.

Mounting options

Do you need a device that can stand or a mounting one? Or you plan to hang it on the wall? The majority of them come with all these options.


Of course, the price is always as significant as other factors. What you should do is take overall properties and features into account, and compare the prices of those products.

In some cases, it’s the name of the brand that sells a product, but it can be a subpar one. On the other hand, you can have a top-performing gadget from a relatively unknown manufacturer. There are no rules. Perhaps some hygrometer with remote monitoring may seem a bit expensive, but in the long run, be sure that they pay off.

Finally, always read reviews from other consumers. Even though manufacturers give their best to provide as much information as they can, there are so many different scenarios. Look at both the positive and the negative ones, they can be of great help.

How Difficult is to Calibrate a Humidity Gauge?

Like I already pointed out a couple of times, the level of accuracy is one of the most critical factors. Without that, you will have a faulty device which won’t be of great help.

Even though most of the products come factory-adjusted, calibrating it yourself definitely wouldn’t hurt. This should be done upon receiving the device, so to make sure you put it into action well-calibrated.

The salt method does the job, believe it or not. What you need for this interesting experiment is a table salt, a container bag that can seal (something like a ZipLock), and a plastic bottle cap.

Types of hygrometer gauges

  • Put a teaspoon of salt in the cap and moisten it with a few drops of water. Be careful not to dissolve it.
  • Carefully place the salt and your gauge into the bag and seal it tightly without removing the air that’s inside.
  • Leave it like that for around six hours and do not open the bag.
  • Read the measure- it should be exactly 75%. If it is not, note the discrepancy as the amount your meter is out of calibration. If the number is lower (let’s say 65), the gauge is 10% low. If it reads 80, the device is 5% high.
  • For an analog gadget, there should be a calibrating screw on the back, so use it to adjust the level to the standard. If you calibrate a digital one using this method, remove the batteries and insert them again before you start calibrating. 

Check your device from time to time and re-calibrate it as the measurements from the sensor can drift over time.

A Couple of Tricks to Adjust Humidity in Your House

When moisture in the air is too high, condensation will appear on walls and windows, resulting in mold spreading all over them. On the other hand, when it is too low, it causes irritated sinuses and dry skin.

Anything between 30 and 40 percent is typically ideal for keeping your place comfortable in the winter, without leaving condensation on the windows. That level grows a bit in the summer, between 50 and 60 percent.

The vast majority of indoor plants thrive in a relative humidity of 70 to 80 percent, which is often a bit difficult to maintain in the home. This particularly goes during the heating season. That’s why we need to find additional methods to boost it.

Use a Humidifier

In case your home needs more humidity, well, quite logically, you’ll have to look for the best humidifier. This way you will either raise the level of moisture in your entire home, or you can do so just in a single room.

They are of great help during the winter when the air is drier, mostly due to heating. That’s why it’s even more important to supervise the levels regularly. When the humidity diminishes a lot, the dryness makes you feel uncomfortable- and the same goes for your plants.

Use a Dehumidifier

If your problem is of the opposite nature, there’s a solution for that as well- have no worries. It is called a dehumidifier, and just as the name says, it decreases the level of moisture in the air.

Get Yourself Plenty of Leafy Plants

If your home has lower humidity you can tackle the issue in a completely natural way- by growing species with lots of foliage. Water from the plants will evaporate into the air, and boost the moisture. This way the plants help themselves, and as a result, you have a greener and healthier home.

Open Windows

During spring and fall, the simplest way to adjust indoor humidity is to open some windows. Doing so not only refresh and cool your home, bit will consequently lower humidity. Plus, you will also benefit from the outside conditions to adjust humidity inside your place.

If you opt for this “regulator”, mind the draft. Even us humans are not always comfortable with it, let alone thin, sensitive plants.

Switch on an Air Conditioner During Hot Months

Cooling your place with an air conditioner can not only lower the temp. but also regulate humidity levels during warm months. Modern “machines” eliminate humidity as part of the cooling process.

But, be extra careful with them. First of all, you should never turn them on if they are not clean. Those bacteria inside can cause you lots of trouble. You could even end up with pneumonia! So, if you want to use this as a method to regulate the humidity, clean it first.

Also, make sure the air is not blowing directly on the plants, it’s not good for them.

Final Thoughts

As you can see, it’s not just about having comfortable or uncomfortable conditions at a specific moment, it’s how they impact your own and your plant’s health.  Aside from faithfully assisting you in adjusting good conditions for your plants, they help you maintain the overall living conditions. By doing so, you minimize any potential issues with colds, dry skin, asthma, and allergies.

Even though all of the devices I described here are indeed excellent, my top choice is Govee Smart Temperature Humidity Monitor (2 pack). It has all the qualities other Govee products have- excellent sensors, large digits, and F/C measuring. And this deal equips you with two devices, for more than an affordable price.
