AN2047 - PSoC® 1 Sensing - Ultrasound Motion Sensor
For Ultrasonic Distance Measurement, refer to AN76530
This application note describes an ultrasound motion detection sensor based on the Doppler-Effect. The sensor is primarily intended to be used in security systems for detection of moving objects. However, it can be effectively involved in intelligent children’s toys, automatic door opening devices, and sports training and contact-less-speed measurement equipment.
