Developer Mishaal Rahman dug into the relevant code and confirmed that Google currently locks the temperature sensor of Pixel 8 Pro, and only trusted applications can call it to obtain relevant data.
According to the information dug by Rahman, developers who want to use the Pixel 8 Pro’s temperature sensor in their applications must have the “com.google.sensor.permission.FAR_INFRARED_TEMPERATURE” permission. However, this permission is currently limited to pre-installed applications or Google signatures. s application.
The report that another developer, Mika, decompiled the Thermometer application and tried to forcibly obtain permissions. Unfortunately, after recompiling, the application cannot read from the thermometer sensor.
Rahman dug further and discovered that each object type has a preset emissivity value. For example, fabrics have an emissivity level of 0.85f, while organic food and beverages have an emissivity level closest to the acceptable value for human skin emissivity, which is 0.98f. Based on these options, Lachman said nearly accurate temperature readings can be obtained.
