Comparison Table of the 8 Best Indoor Outdoor Thermometers

Why Have an Indoor-Outdoor Thermometer?

The primary purpose of a thermometer that you can use indoors and outdoors is to gather information about the temperature without having to move.

If you are lazy to go down the wine cellar, just check the reading provided on the device mounted on your wall to see if the temperature is within the acceptable range. And if it’s too cold to check outside, you can consult the display on your thermometer for readings.

Some thermometers also give you an accurate reading of the time, humidity, and barometric pressure of your surroundings.

Some places you can put your indoor-outdoor temperature monitor in include the baby room, refrigerator, greenhouse, and barn. You can also use them on cars and trucks that carry snow or ice.

Do Indoor-Outdoor Thermometers Have Extra Features?

Some indoor-outdoor thermometers let you tell the time through their clock feature. Others have a hygrometer function that allows you to determine the humidity of your surroundings.

Trend arrows also let you know if the temperature is rising or going down. Other extra features include weather forecasts, graphical representations of the weather, barometric pressure, and the moon phase.

Can I use an indoor-outdoor thermometer in an apartment or rental unit?

Yes, you can. Wanting to monitor the temperature of your rental unit does not violate any rule as long as you do not drill holes to hang the thermometer on the wall. Most indoor-outdoor thermometers let you sit the device on top of a flat surface.

Features of the Best Indoor-Outdoor Thermometers

Most thermometers now fit modern smart homes because of their sleek design and impressive performance. If you want to make a practical purchase, here are the most essential features to look for in an indoor-outdoor thermometer.

Accurate Readings

Accuracy is the most vital aspect and notable feature you should consider when deciding on an outdoor or indoor thermometer. For things such as barometric pressure readings, humidity trends, environmental conditions, and temperature accuracy.

These devices usually don’t have the same temperature range indoors and outdoor, so it’s best to choose one with the highest possible range to give you more reliable data 24/7.

Such range will allow you to place the device in areas with extreme temperatures like your yard or freezer.

If you need it for outside, make sure to get one with an outdoor sensor that can withstand a list of weather conditions such as wind, water, direct sunlight, and other things.

Thermometers usually arrive pre-calibrated already, meaning they provide accurate data straight out of the box. But it should still have an option for you to manually calibrate it.

Hygrometer Function

Some may find the hygrometer function unnecessary, but you also have to gather information about the humidity of your household. For example, if you have allergies or asthma, you will benefit from a hygrometer to ensure that the space isn’t too dry or humid.

If you have cigars at home, you need to make sure that the flavor and aroma don’t get dried out by the environment. You can also prevent cracks on your guitar if they are kept at a safe temperature and humidity levels.


The size of your indoor-outdoor thermometer depends purely on your preference. But you need to take note that the larger the display screen, the more readable the digits are.

With a digital display screen, you will need bigger numbers and symbols that do not feel cramped.

Some thermometers also feature a backlight so you can read the information even in the dark with a bold display. You can also get some models with color displays to differentiate between each mode such as the humidity gauge, temperature, and more.

The display size and display unit also come into play here. Whether you have an indoor unit or one placed outside, make sure you get a model that has a large enough display screen to show the indoor or outdoor readings in an easy-to-see manner.

To sum up, make sure you have a unit that has:

  • Current temperature
  • Daily temperatures
  • Attractive display
  • Easy-to-read display
  • Air temperature
  • Ground temperature
  • Outdoor temperature reading
  • Indoor temperature reading
  • Humidity monitor and humidity level
  • Display of time
  • Weather forecasting
  • Atmospheric pressure

Can Be Placed Anywhere

If you’re placing your sensor outdoors, you should be able to hang it to a hook or mount it on the wall. If you’re keeping it indoors, make sure it can be mounted on the wall or placed on top of a flat surface.

Multiple mounting options give you tons of choices on the strategic places to leave your thermometer. Just don’t put it near an appliance that radiates heat to keep the temperature readings accurate.

The same goes for humidity. Be mindful of where you place it so as to not cause the humidity sensor to perform incorrectly. If you’ve got an air conditioner, dehumidifier, or humidifier, these will all affect the readings.


An affordable price is just as important as a good warranty in a wireless temperature sensor. You need an indoor-outdoor thermometer that lets you get more than your money’s worth. You can get very affordable ones that are complete with trend arrows, a hygrometer, a backlight, and a wide range of transmissions. But you also have to make sure that they will last a long time, especially in extreme conditions.

Battery Life

Digital models need batteries. The longevity of your batteries depends on what type you choose for your indoor-outdoor thermometer. Rechargeable batteries are recommended, not only for their quality but for their ability to reuse them. Lithium batteries are one of the more common types and an ideal choice for battery power.

Indoor and outdoor thermometers are an asset at home, so it’s just right that you pick the best one with complete features at a reasonable price. ThermoPro TP60S wins the battle of indoor-outdoor thermometers, followed by AcuRite 00424CA and SMARTRO SC 92.

This makes it perfect for those with large properties where the sensor might be too far from the base unit. You can also connect ThermoPro to multiple sensors, unlike the Taylor Wired Thermometer, which stands alone.

This way, you can monitor the temperature of multiple household locations at once.

Most importantly, a good indoor-outdoor thermometer provides accurate readings of temperature levels, so it’s a good thing that ThermoPro has an indoor temperature range of -4°F-158°F and -58 °F-158°F for outdoors with an additional hygrometer function.
