MS8891 "Human Body Detector"
The MS889X-series are capacitive sensors and switches that have been specifically developed for use in “Wearables“. When the MS889X functions as a switch, an external sensor capacitance is compared to a programmed threshold to detect whether the external value lies above or below the threshold.
