Presence Detection

Ultrasonic Presence Detection

TDK InvenSense’s presence detection software turns our MEMS based ultrasonic time-of-flight (ToF) range sensors into intelligent and configurable presence detection sensors right out of the box. Software packages—capable of being run on the ultrasonic ToF sensor’s ASIC or the host processor—are ready to go so you can accelerate development of your next Presence Detection design.
