There is a temperature and humidity sensor that has been present in the HomePod mini since its launch, but which has not been used or announced.
Lost all demolition at launch, the HomePod mini is now revealed to have a sensor that is likely planned for future use. There are no specific details about its function or limits yet, but it is a sensor that measures temperature and humidity.
Conformable Bloomberg with assistance from I’ll fix it, Apple has internally discussed the deployment of the sensor to relay this data to other devices. Unspecified sources say it could be used to help thermostats connected to the internet.
Similarly, sensor readings that are not in a good location to determine component temperatures could be used to trigger HomeKit actions. Potentially, a user could set a HomeKit compatible fan to turn on when the HomePod mini reports that the camera is reaching a certain temperature.
The sensor is located at the base of the HomePod mini, next to where the power cord enters the unit and is about the size of a grain of rice. Apple has not commented on its existence, and its HomePod mini technical specifications do not list its presence.
However, like all Apple devices, these specifications list the operating parameters of the environment. HomePod mini is intended to be used only between 0 degrees Celsius (32 degrees Fahrenheit) and 35 degrees Celsius (95 degrees Fahrenheit).
Similarly, it is intended for use only when the relative humidity is what Apple describes as “5% to 90% without condensation.”
