By using the best hygrometer thermometer, also known as a digital humidity meter, you can accurately measure the moisture level and temperature in a room. This helps you decide whether you need a humidifier or dehumidifier in your home.

What is a hygrometer used for?

A hygrometer is an instrument that measures how humid the air in a room or space is so that you know whether the air has too much moisture or not enough moisture. This will help you decide whether you need to buy a humidifier or you need to buy a dehumidifier, or whether there are other things you should be doing to reduce humidity or increase moisture in your home.

It’s one of the first steps to take when you’re trying to either add moisture in your home or remove humidity, which is something we go into more detail when looking at how to dehumidify your bathroom.

Best Hygrometer Reviews 2020


The SensorPush wireless thermometer and hygrometer is one of the best digital hygrometers in 2019. It’s been designed with you in mind- you’re a busy person. The right temperature and humidity is important to you but you have other things to worry about. It would be easier to have humidity taken care of without much fuss.

The SensorPush has a Swiss-made sensing compontent that’s accurate and reliable when measuring temperate and humidity.

You can set the ideal humidity level you want and then forget about it. You’ll receive an alert on your phone if there’s an issue or problem. The hygrometer is monitoring the conditions in your room even while you’re sleeping or while you’re out at work.

You can receive data and alerts via the internet by purchasing a SensorPush G1 WiFi Gateway. You can monitor your readings via an easy-to-use app that’s compatible with iPhone and Android.

For those who love monitoring data, you can use the app to view your data or you can download a CSV file to use in MS Excel.

The SensorPush stores the last 20 days of data. This is great for if you’re going away or if you don’t have access to the internet while you’re out.

Your one mobile device can monitor an unlimited number of sensors. You can purchase extra sensors if you need more than one room monitored. One sensor can also be monitored by multiple mobile devices. If there’s more than one person in your household, then all of you can monitor the device. This is great if you’re too busy or away, and your partner or someone else in your family is able to monitor the data.

Can you use the device wirelessly? Yes, up to 100 metres without obstructions. In a normal home this is usually sufficient. You should be able to walk around your home and read the data from any room or place including your basement and when you want to dehumidify your garage or you want to dehumidify your bathroom.

Can you use the sensors outside? No. The SensorPush is not waterproof. It is meant to be used as an indoor hygrometer. It can be used outside but only in places that are protected from snow, rain and frost. A covered outdoor area is more suitable.

The battery needs to be replaced about once per year.

If you need humidity and temperature readings for different areas in your home, then the Ambient Weather WS-10 will allow you to do this.

The Ambient Weather WS-10 is a great option for those looking for a digital thermo hygrometer. Inside the main console, there is an indoor thermometer/hygrometer with an additional 3 thermo/hygrometer sensors displaying information at the same time. The system can use up to 8 sensors- only 3 sensors are included in the price when purchasing the Ambient Weather WS-10, however additional sensors can be purchased.

If you’re looking to buy an outdoor thermometer hygrometer, you’ll be happy to know that the Ambient Weather WS-10 can be used outside.

There is a display on the actual sensors as well on the main console- so you can check your main console to obtain the readings of the additional sensors.

Even though the information can only be displayed for up to 4 sensors, if you have more than 4 sensors there is a scroll through mode available. The display unit automatically scrolls through up to 8 of the sensors without you needing to do anything.

The console display shows you the temperature and humidity, with both a minimum and maximum value.

What we love about the Ambient Weather WS-10 is that you can set a minimum and maximum humidity level, and when the room reaches this level, the display console has an audible and visual alarm to let you know. This will help you know when you need to adjust the humidity and temperature in a room. Note that this feature is not possible for sensors located outside.


  • Being able to measure multiple temperature and humidity levels at the same time both indoors and outdoors
  • An excellent choice for large homes with many rooms
  • Audio and visual alarms to indicate when a temperature/humidity level has been reached


  • The alarm feature is only possible in indoor locations
  • Can be costly when adding up the additional sensors and batteries required
  • Is more complex to set up initially

Regardless of where you live, whether it’s in a tropical region or somewhere cold where you constantly use heating, your home’s air quality will impact your comfort and health.

It’s important to know the humidity level in your home. If the humidity is too high, you’ll  want to use a dehumidifier. If the humidity is too low, you’ll want to add moisture to the air via a humidifier.

The best way to check the humidity level in your home is by measuring it using a hygrometer. Make sure you have an understanding of optimal humidity levels- this isn’t just something people in the tropics need to know. If you’ve ever suffered from a dry cough in the middle of winter, it’s probably from a low humidity level. And your bathroom is sure to be humid especially after it’s been used, so a hygrometer is perfect for checking humidity levels so that you can plan on how to dehumidify your bathroom.

I’ve written this product review article so you can choose the best digital hygrometer for your home, but also so that you can learn more about humidity and how a hygrometer can help you. Make sure you choose the most accurate hygrometer for home use.

What is a digital hygrometer?

A digital hygrometer measures the level of moisture in the air and gives you a measurement as a percentage. It tells you roughly how much moisture is in the room. This can help you decide whether you need to switch on your humidifier or dehumidifier.

Hygrometers are typically used by meteorologists and also in any industry where it’s important to know moisture levels (such as when you’re painting, using a greenhouse or working with chemicals).

But hygrometers are also used in homes and offices- they help people adjust the moisture levels in their homes. This is important for comfort and to prevent problems such as mold, which can occur in small, dark spaces such as bathrooms and basements.

Other uses for hygrometers include preserving cigars, using incubators to hatch eggs, in saunas and hot rooms and keeping your wooden musical instruments in good condition.

Why should I use the best hygrometer?

Types of hygrometers

The two main types of hygrometers are digital hygrometers and analog hygrometers. Digital hygrometers are the most commonly used in households, so these are the ones I’ve reviewed in this post.

How To Choose The Best Hygrometer

How can you find the best digital hygrometer for you home?

When I was researching and reviewing digital hygrometers currently on the market, I considered the following:

Ease of use


Battery life





When you read about digital hygrometers, many consumers talk about the accuracy of the measurements. This is one of the biggest pitfalls of a digital hygrometer- you will always find a difference in measurement from one digital hygrometer to the next. There are always slight variances, and it’s very difficult to get a reading that is 100% accurate. You want the most accurate hygrometer for home use.

If you keep this in mind when choosing a digital hygrometer, you won’t be disappointed. For each hygrometer I’ve reviewed, I’ve mentioned how accurate the hygrometer is. Some are better at accuracy than others.

When choosing the best digital hygrometer, think about the space where you will be using the hygrometer and how many rooms you’d like to measure. If you need it for multiple rooms, particularly if you have a large home or live in a tropical environment, you’d need to choose a digital hygrometer that has more than one digital sensor and can perform multiple readings.

Why Should I Buy A Digital Hygrometer?

Most humidifiers now come with a built in humidistat, which is essentially a type of hygrometer. Humidifiers use the humidistat to determine whether the desired humidity level has been reached- and once it reaches this level, the machine usually shuts off.

However, humidistats are not always accurate, and may only measure the humidity level in the surrounding area of the home. To get a more accurate reading of the humidity level in an entire room, you’d be better off buying the most accurate hygrometer.

A hygrometer is a humidity measuring device that measures how much water vapor is present in the air. It displays the humidity level as a percentage. This helps you decide whether you need to humidify or dehumidify a room or your entire home, depending on your personal needs.

For example, an asthmatic or person with other respiratory problems would want to prevent dryness in the air, which can irritate the respiratory system. By using a digital hygrometer, an asthmatic person can keep an eye on moisture levels and when they drop below a certain point, they can switch on their humidifier.

A digital hygrometer can also help you measure how humid a room is so that you can adjust the humidity levels and prevent mold and bacteria build up. Some areas of the home are more prone to humidity such as bathrooms and laundries. This can lead to paint and furniture damage as well as respiratory issues.

If you are looking for a digital thermo hygrometer, you won’t have trouble finding one that can measure both temperature and humidity levels.

If you are budget-conscious or someone who prefers to reduce energy consumption for environmental reasons, using the best indoor hygrometer can help you with this. Rather than leaving a humidifier to run for hours, a digital hygrometer can let you know when your desired humidity level has been reached. Some digital hygrometers have an alarm that will let you know. You can then switch on or off your humidifier or dehumidifier, potentially saving you money on your energy bills.
