AEK-SNS-2TOFM1 Gesture Detection System

STMicroelectronics' redefined gesture detection system is based on FlightSense™ technology sensors

Image of STMicroelectronics AEK-SNS-2TOFM1 Gesture Detection SystemSTMicroelectronics' AEK-SNS-2TOFM1 includes two time-of-flight distance ranging sensors placed at 23 cm apart. The onboard SPC582B microcontroller reads sensor data and detects a predefined hand or foot gesture. This solution was conceived for the power liftgate application to open and close a trunk with a predefined foot movement.

The AEK-SNS-2TOFM1 board firmware is preloaded and enabled for external CAN bus driving. The AutoDevKit software library (STSW-AUTODEVKIT) shows a CAN bus driving example based on SPC58EC Chorus 4M.
