A sensor hub is a microcontroller unit/coprocessor/DSP 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]

Starting from Cherrytrail, multiple generation of Intel processors offers on package sensor hub.

Intel has the Intel Integrated Sensor Hub.

Samsung Galaxy Note2 is the first smart phone with a sensor hub, which was launched in 2012.


Some devices with Snapdragon 800 series chips, including HTC One (M8), Sony Xperia Z1, LG G2, and on, have a sensor hub, the Qualcomm Snapdragon Sensor Core,[4] and all HiSilicon Kirin 920 devices have sensor hub embedded in the chipset with its successor Kirin 925 integrated an i3 chip with same function into it.[5] Some other devices that are not using these chips but with a sensor hub integrated are listed below:
