Indoor thermometers are important assets for most homeowners. You can use them to check the efficiency of your heating system, to make sure you have a healthy temperature in your home, or to monitor the temperature in other enclosed spaces, such as a greenhouse, hatchery, or wine cellar. The models evolved over the years, and now, the best indoor thermometers feature digital displays, hygrometer function, and app connectivity, to name just a few. They fit perfectly into trendy smart home designs but are still as easy to use as the conventional models.
With so many devices on the market, though, choosing the best indoor thermometer is far from easy. That’s why we did the hard work for you, roaming the market and finding the most promising models. Curious to know which made it to our list? Check them out below.
The Best Indoor Thermometer
1Govee WiFi Digital Hygrometer Indoor Thermometer
The Govee WiFi Digital Indoor Hygrometer Thermometer might be the best choice for most homeowners. It combines the functionality of an indoor thermometer with that of a hygrometer, helping you measure both the temperature and the relative humidity in your home.
Its greatest highlight is the high-precision built-in sensor developed to deliver accurate readings. Thanks to this technology, you can rest assured you’ll get reliable data each time. A switch temp function gives you the possibility to check the temperature in either Celsius or Fahrenheit. Furthermore, the simple one-button design makes it easy to calibrate the unit and set temperature or humidity alarms.

2Veanic Mini Digital Indoor Thermometer
If you primarily want to monitor humidity rather than temperature or look for a hygrometer-thermometer that doesn’t break the bank, then the Veanic Mini could be the best device to get your hands on. As its name suggests, it is a two-in-one meter with a built-in probe for both indoor temperature and humidity.
Rather basic functionality makes it ideal for those who appreciate simplicity. There are no complicated functions to set up, no alarms, and no app connectivity. While some might think of it as a drawback, quite a few users see it as a blessing. Its compact size adds versatility to the game, allowing you to place it in most spaces. Whether you want to measure the temperature and humidity in your fridge, in the rooms, or in a greenhouse, this indoor thermometer makes it all possible.

3ThermoPro TP50 Digital Hygrometer Indoor Thermometer
The ThermoPro TP50 might be mistaken for a cheap indoor thermometer, but don’t be fooled by its looks. This is a highly accurate device designed to help you maintain optimal living conditions in your home. An array of features make it worthy of the best indoor thermometer title. The one we like best is the smiley face air comfort indicator that lets you know whether the air in your room is too dry, too wet, or comfortable.
Smiley face apart, the unit also displays the actual humidity level, so that you can always be aware of any environmental changes. Like our best value, it measures temperature in the -58°F-158°F range. Daily high and low records – as well as the current temperature – make it perfect to use in your rooms, but also as a cigar hygrometer, to check the temp in your fridge or freezer, and more.

4Govee Thermometer Hygrometer
This Govee Thermometer Hygrometer is a less technological – as well as less expensive – version of the Govee above. The main difference between the two is the lack of Wi-Fi connectivity on this model. Design-wise, this indoor thermometer is rectangular with rounded edges rather than oval, a wiser choice for those who look for a larger display and don’t really care about Wi-Fi connectivity or other bells and whistles.
But just because it lacks Wi-Fi, it doesn’t mean that you can’t control it from a distance. The device connects with the Govee Home app via Bluetooth, letting you check the temperature and humidity at all times and sending alerts when they are out of a pre-set range. Thanks to this intelligent function and a remote range up to 260 feet, the unit is suitable to use in your home and not only. Like our top pick, this device comes with the Swiss-made SHT30 sensor that provides high-accuracy monitoring in most enclosed spaces, from your rooms to a greenhouse or wine cellar. If you also wish to be able to track the temperature both inside and outside at the same time, check out our selection of the best indoor outdoor thermometers and find the right one for your home.

5Habor Digital Hygrometer Indoor Thermometer
The Habor Digital Hygrometer Indoor Thermometer is one of the simplest models on this list, but we like its ease of use and accuracy. Don’t expect anything fancy, such as wireless connectivity or integration with your mobile or smart home devices. However, this mini temperature and humidity monitor comes with a wealth of pluses. Its greatest strength is the high accuracy and reliability. The unit uses 24 sensitive vents to provide accurate readings, which are updated every 10 seconds.
Maybe the range is not the widest, but considering that this is an indoor thermometer, the temperature from 32°F to 122°F and humidity from 20% to 95% ranges are still sufficient. Indeed, these ranges make it an excellent choice not only for your home, but also for a garage, greenhouse, cellar, or even an RV.

6Govee Temperature Humidity Monitor
Next entry on our list of best indoor thermometers is another Govee temperature and humidity monitor. Half-way between our top pick and the budget option above, this model impresses with higher Bluetooth covering range and better compatibility with Apple and Android devices.
Like most Govee’s, the unit boasts precise sensors that deliver reliable, accurate data. Two display modes let you see either the current temperature and humidity or access historical data. Similar to the H5051 model, the unit can store up to 20 days of data, and you can even choose to record and export up to two years’ worth of readings. The 328 feet Bluetooth covering range make it a tad more attractive than its H5075 counterpart. Similar to other Govee units, it works with the Govee Home app to let you monitor the temp and humidity from a distance. Not as expensive as the H5051 but more feature-packed than the H5075, this is a great choice if you’re looking for the best compromise between price and functions.

7ThermoPro TP53 Hygrometer Indoor Thermometer
The ThermoPro TP53 is nothing but the upgraded version of the TP50 above. Why isn’t it our premium pick, then? Well, the truth is that the design differences and upgrades are so minimal that we couldn’t justify the slightly higher price of this version. That said, the TP53 still has an extremely attractive price tag, and it could be a better choice if you’re looking for more bells and whistles.
The main difference between the two is the light-up screen on the TP35. The backlit display is obviously easier to read in dim light, and you won’t have to turn the lights on if you want to check the temp or relative humidity in the middle of the night.

8AcuRite 01083 Indoor Thermometer and Hygrometer
Designed to deliver professional-level accuracy, the AcuRite 01083 features high-precision sensors and is able to provide reliable measurements and fast data reporting. All packed in a compact device you can place on a tabletop, mount on a refrigerator, or even take with you on your adventures. Similar to the other devices on this list, this is an indoor thermometer and hygrometer developed to help you keep optimal levels of temperature and humidity in your home or enclosed environments.
Although it comes pre-calibrated, we like that you can also calibrate it manually if you want to. This feature guarantees higher precision, so you can rest assured the displayed readings are real. The temperature range might not be the widest out there, but it’s still optimal for an indoor device, measuring from -4°F to 158°F. Furthermore, the humidity gauge detects levels between 1% and 99%, making the unit ideal to keep in a greenhouse.

9VIVOSUN Digital Indoor Thermometer
VIVOSUN is another brand that came up with an optimal solution for monitoring the temperature and humidity in your home or enclosed spaces. The VIVOSUN thermometer is a simple device that can be placed on a desk or counter, hanged on a wall or mounted on a fridge, and it impresses with a digital touchscreen instead of conventional buttons. Not only it’s enough to touch the screen to turn on the backlight, but you can also switch from all-time to 24-hour lows and highs, as well as from Celsius to Fahrenheit.
As you can expect, the monitor provides reliable readings, and it even features the popular humidity comfort level indicator bar. We particularly like the large display that allows you to see the temperature and humidity from a distance, while the two AAA batteries needed to run the gadget are included in the pack.

10AcuRite 00325 Indoor Thermometer and Hygrometer
The last entry on our list is the AcuRite 00325. Design-wise, it’s not as fancy as its 01083 counterpart above, but it still packs a punch. This monitor delivers accurate readings, and it’s suitable to use in your home, office, as well as many other indoor environments.
Despite its pretty basic look, it still has a large-enough display that shows all relevant data. Large digits make it easy to spot the current temp and humidity at a glance, while 24-hour low and high records allow you to monitor both the air quality and the overall efficiency of your heating or air cooling system. A nice twist is the humidity comfort level indicator consisting of a house icon with low, ok, and high marks instead of a bar. There are no other fancy features apart from this. Don’t expect a backlit display nor colorful marks. Considering its accuracy and price, though, the AcuRite 00325 is still an excellent choice for the money.

Indoor Thermometer Buying Guide
Features To Look For In An Indoor Thermometer
There are dozens of thermometers out there, and finding the right one is not always easy. Here are a few features to look for in the best indoor thermometers.
Temperature accuracy – This should go without saying, but the most important thing to look for in an indoor thermometer is its accuracy. Most manufacturers sell their units pre-calibrated, and they should read the temp accurately straight out of the box. However, if you want to have more control, you should opt for an indoor thermometer you can calibrate manually.
Temperature range – While all indoor thermometers have a range wide enough to measure the temperature in a home or office, you should go for the widest possible range if you want to place the device in a greenhouse, wine cellar, or if you plan to use it to measure the temperature in your refrigerator, for instance.
Hygrometer function – Temperature is only one of the factors you should monitor in your home. Humidity is important too, especially if you suffer from allergies, asthma, or other respiratory or skin conditions. Luckily, most indoor thermometers nowadays feature humidity gauges.
Display – Make sure the display is large enough to allow you to see readings at a glance. If you want to check the temp in dim or no light conditions, pick a unit with a backlit display.
Connectivity – In the era of smart homes, connectivity features come as a bonus. The best indoor thermometers can connect with your smartphone either via Bluetooth or Wi-Fi, allowing you to check the temperature or receive low/high temp/humidity alerts even from a distance.
Types Of Indoor Thermometers
Besides features, another thing to decide before buying is what type of indoor thermometer you need.
Analog thermometers – Are the simplest and oldest models. They consist of a glass tube filled with mercury or an alcohol mix that expands in volume as it gets warmer. A scale makes it easy to read the temperature, but these models are not the most accurate. However, they are cheap and have long lifespans.
Digital thermometers – These modern alternatives to the analog thermometers use various technologies to measure the temperature and conveniently display the results on LCD screens. Nowadays, digital thermometers are the standard in most homes, and some even connect with your smart devices to allow you to record and access current and historical data.
Indoor/outdoor thermometers – A hybrid between an indoor and an outdoor unit, the indoor outdoor thermometer is a great choice for those who want to keep an eye on both the indoor and outdoor temps. They’re usually more expensive than the digital indoor units, but give you access to more data, including temperature, relative humidity, barometric pressure, and sometimes even weather forecasts.
