Apple's HomePod Mini Speaker Comes With Secret Inside

Apple Inc.’s HomePod mini speaker launched last November with new features such as a home intercom system. But one part of the device has remained secret: a sensor that measures temperature and humidity. 

The Cupertino, California-based technology giant never disclosed this component and the device currently lacks consumer-facing features that use it. The company has internally discussed using the sensor to determine a room’s temperature and humidity so internet-connected thermostats can adjust different parts of a home based on current conditions, according to people familiar with the situation. The hardware could also let the HomePod mini automatically trigger other actions, say turning a fan on or off, depending on the temperature.
