Sensor hub explained

A sensor hub is a microcontroller unit/coprocessor/DSP set that helps to integrate data from different sensors and process them.^[1] This technology can help off-load these jobs from a product's main central processing unit, thus saving battery consumption^[2] and providing a performance improvement.^[3]

Intel has the Intel Integrated Sensor Hub. Starting from Cherrytrail and Haswell, many Intel processors offers on package sensor hub. The Samsung Galaxy Note II is the first smart phone with a sensor hub, which was launched in 2012.

Examples

Some devices with Snapdragon 800 series chips, including HTC One (M8), Sony Xperia Z1, LG G2, etc., have a sensor hub, the Qualcomm Snapdragon Sensor Core,^[4]
