Indoor and Outdoor Thermometer Buying guide

So, these were the reviews of the top 7 best indoor outdoor thermometers available in the market.

You can shortlist 2-3 thermometers that fulfill your broad requirements.

I would recommend that you refer to our buyer’s guide below to get more insights about these special types of thermometers. This will help you in selecting the most suitable thermometer for your purpose.

What is an indoor-outdoor thermometer?

What is an indoor-outdoor thermometer?

An indoor-outdoor thermometer is a special thermometer used to measure the temperature inside and outside a building simultaneously.

The device comprises a thermometer to measure the inside temperature and a remote temperature sensor to measure the outside temperature. It has a screen to display both these temperatures.

What to Consider When Buying an Indoor-Outdoor Thermometer?


Accuracy is one of the most vital factors of any instrument. The thermometers used for residential purposes normally work within an accuracy level of ±2oC. 

This is fine if you use it to plan your daily activities as per the weather conditions like dressing up etc. However, those using it to regulate temperatures in their grain stores or greenhouse would require a more accurate thermometer.


Most thermometers use screens to display the indoor and outdoor temperatures of the building. However, there are a few important display aspects that you should consider while finalizing a thermometer. These factors would help you to get the right information whenever you need it.


The screen size and the fonts are the primary aspects of a good readability. Larger screens offer a clear vision of the displayed readings.

The bigger font size allows you to view the temperatures from a distance. The viewing angle also affects the readability; mainly, a reflection of sunlight on the screen can make it difficult to read the correct readings.

Some models also have a backlight that allows you to view the readings in the dark. 


Different models use different types of power sources. For example, some models use the main powers, while others use the battery as the power source.

Batteries often cannot support the large display screen for a long duration and lose their power quickly, thus dimming the screen brightness. Another flip side with the battery-powered model is that you need to either replace the battery frequently or use rechargeable batteries.

However, battery models offer higher portability than the main power outlet.

The most recommendable option is to have the display screen powered through the main power and backed up by the battery during the power interruption. 


The mounting of an indoor-outdoor thermometer is also a significant factor to consider from multiple angles. Though the thermometers have their inherent accuracy level, the sensors’ mounting can significantly affect the accuracy of temperature readings.

Indoor mounting options should also get similar importance as the outdoor sensors. The indoor display units also have in-built thermal sensors to measure the temperatures.

The display unit comes with varied options. Some come with free-stand tabletop mounting, and others have wall mounting arrangements. The power source would also be a deciding factor for the type & location of mounting.

It would help if you mounted the display powered through the main power outlet near the power socket. However, a battery-powered display would have the flexibility to mount anywhere at your convenience. 

Take care to mount the display far away from the devices radiating heat as they can interfere with the sensor function and show incorrect temperature readings.

For the outdoor mounting, select a shaded open location not affected by harsh weather conditions. Like the indoor unit, install the outdoor sensors away from the radiating heat devices.

Remote Monitoring

It would help if you had a WiFi-enabled model to monitor temperatures remotely on different devices like your PC, tablet, or smartphone. You can even share this data with other devices. Many high-tech models offer a straightforward method to set up connectivity with multiple devices.

Barometric Pressure

The air continuously exerts pressure on the earth’s surface; Barometric Pressure measures this continuous air pressure. Advanced thermometers also can measure barometric pressure.

The barometric pressure readings are beneficial in forecasting weather conditions. For instance, if the barometric pressure is high, it indicates low temperatures to pull the clear skies.

On the other hand, low air pressure indicates high-temperature air rising in the atmosphere and may cause strong winds to form and accumulate clouds.  

Barometric pressure monitoring is generally recommended for barometric pressure changes that bring drastic changes in weather conditions.


To select the model, you should first determine the distance between the outdoor sensor and the location you are planning to mount the display unit.

However, this still would be a rough estimate. The thick walls between the sensor and the display unit can seriously affect the range. Besides, the wireless signals emanating from cell phones and internet devices can also affect the appliance range.

So, get a device with a higher range than the distance between the two devices, and while mounting both the devices, try multiple locations to find out and finalize the location showing the most accurate readings.

Final Thoughts

Selecting a good indoor-outdoor thermometer from among the numerous varieties available in the market can be daunting.

However, the task becomes pretty simple if you have the correct information. With this article, we have tried to provide you with relevant information to help you make the right decision while buying the best indoor-outdoor thermometer for your specific needs.
