9 Best Apps to Check Room Temperature for Android

Mobile app developers have already learned how to embed an entire working thermometer into your phone. Now it’s possible to throw away all thermometers from the house. You just need to download the appropriate app and start using your phone as a measuring device.

Is it possible to measure temperature accurately?

Since an integrated sensor is used to measure temperature, the applications reviewed don’t have the highest accuracy. For plausible readings, it’s recommended to adhere to several rules.

  • It’s necessary to run a pre-calibration, if such option is available in the application.
  • Before running the program, the phone should be inactive (at least 10 minutes) to allow the internal components to cool down. If the mobile device has been on charge or has been in the owner’s hands for a long time, the measurements will be erroneous.

Most of these programs are completely free. Let’s take a look at some popular temperature measurement apps that can be downloaded from Google Play.

Heaveen Thermometer

This app is capable of turning any smartphone into an accurate thermometer.

After launching it for the first time, go to the section called “Calibration”. This is where the readings will be recalculated and the accuracy of the measurements will be improved.

The application has a great interface, made specifically for the convenience of the user.

The parameters are displayed in a special highlighted column of the mercury thermometer, and the results of the measurements are located below it.

Please note that there may be a slight error margin in the measurements. This should be taken into account when measuring the temperature in the room.

It’s also necessary to carry out a proper calibration before each measurement. Prior to this, you should not load the phone, as any heating of the internal parts will adversely affect the accuracy of the temperature measurement.

It’s important to note that the accuracy of such measurements can be inaccurate. This is due to the use of a temperature sensor designed to register the overheating of built-in components, not the environment. The readings will vary between 3 and 7 degrees Celsius.

However, if you follow the instructions, you can achieve an accuracy of up to 3 degrees. To do this, you need to calibrate and not use your smartphone for some time before you start measuring so that the components of the gadget are not heated.
