Best Indoor Thermometers Of 2022 For Temp Monitoring
Indoor thermometers are incredibly useful and versatile little devices that can help you maintain optimal conditions in your entire home – and more. Firstly, with a thermometer, you can check the efficiency of both your cooling and heating systems to ensure they are working properly. Maintaining the right temperature in your home is also essential to your family’s health and wellbeing: too hot and you all face being uncomfortable, while too cold can result in family members being more susceptible to colds and flu. A thermometer is also essential in places like a greenhouse, hatchery, or wine cellar where monitoring and maintaining the right humidity and temperature levels is important.
While a simple old-school thermometer is fine, today’s indoor thermometers feature a digital display and a hygrometer function. You can also take advantage of app connectivity to ensure your home stays at the right temperature, especially if your home’s heating and cooling system can also be controlled remotely.
With so many devices on the market, though, choosing the right indoor outdoor thermometer for your needs and budget can be challenging. That’s why we did the hard work for you, scouring the market for the best indoor thermometers with the most useful features and smartest sensors.

The Best Indoor Thermometer
The ThermPro TP50 home hygrometer/thermometer offers accurate and precise readings between -58 degrees and 158 degrees Fahrenheit. So unless you live in the Gobi desert or the Arctic tundra, this device has you covered. I have used this in the main area of my home for the last eight months, and I recently moved it into the interior of my van. I am currently building out the van and added the thermometer to track humidity and temperature to ensure I am comfortable while camping and that the build-out I’ve worked so hard on is effective.
The single AAA battery that comes with this product is still going strong, and I have had zero lapses in performance. I appreciate the ability to set up this monitor in three ways. You can hang it, which is my mode of use in the van, set it up on a table which is how I used it in my home, or use the magnetic back to attach it to the fridge. Read the in-depth review here.

The Govee Smart Hygrometer/Thermometer is a Bluetooth-enabled device that allows you to check the conditions of your chosen location from your smartphone. The 262ft connectivity range means you still need to be usually within your home to use the device, but it’s much faster to pull up the app than walk across your home to check a screen. It also has graphs that show recent changes so you can identify problems quickly.
When I first got this device, we popped it into a crawl space turned storage area where my roommates and I keep much of our outdoor gear. Shortly after placing it, we noticed very high humidity and pulled out some gear to find mold beginning to pop up. Had we not used Govee, we may have lost the bulk of our gear to mold! Given that my outdoor gear is the bulk of my net worth, this is a big deal. My roommate fixed up the space, and Govee lives in there permanently now, so I can always check the status of my beloved gear and ensure it’s in a safe space, especially during changing seasons and the rainy winters here in the PNW.

Why Trust Us
No one knows gadgets quite like we do, including indoor thermometers that we happen to find extremely beneficial. We have taken the time to test a few models to see how well they actually work and in what ways indoor thermometers could be useful. It turns out, they are not only a great way to regulate the temperature in your home and to keep an eye on how well your home's heating and cooling systems work as well as the ambient moisture in the air, but are also crucial for storing expensive gear the right way.
Who This Is For
Our comprehensive guide to the best thermometers is for anyone who wants to ensure their home environment is comfortable and to monitor temperature and humidity levels. This is especially important if you have family members with respiratory conditions where maintaining healthy air quality is essential.
Cooling or heating a home can be expensive, but if your systems aren't working efficiently, they can use even more power. An indoor thermometer can effectively let you know if your systems are working properly and this can save you on power and repair bills.
How We Picked
We looked at dozens of indoor thermometers to find the best ones for use in the home, office or even a storage facility. We picked the ones that were affordable and the easiest to set up and use but, more importantly, were reliable in terms of accuracy.
How We Tested
The only way to test indoor thermometers is to use them at home and work and see how accurate they really are - which is exactly what we did with a few thermometers from this list. We tested them for ease of use, placing them in different areas, as well as checking some of the additional features to see how worthwhile it would be to have an indoor thermometer in a visible place where one could make use of the readings on the interface.
Features To Look For In Indoor Thermometers
There are dozens of thermometers out there, and finding the right one is not always easy. Here are a few features to look for when shopping for an indoor thermometer.
Size - The devices in this guide are all compact which makes them ideal for keeping on a desk or countertop but most can also be mounted on a wall or on the fridge. What is more important though is the size of the display so look for a unit with a display with numbers that are large enough to see even from a short distance.
Temperature accuracy – This should go without saying, but the most important factor when looking for 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.
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.
Battery life - The battery life in indoor thermometers may not be easy to predict as there are certain factors to consider. Some models will simply use less power than others and if the one you have chosen has a backlight, you can expect to change the batteries more frequently. On average though, you shouldn't need to change the batteries more than twice or three times a year.
Types Of Indoor Thermometers
Analog thermometers – These 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 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. If you want a proper outdoor weather station, check out our guide to the best indoor-outdoor thermometer units.
