We've Got A New Toy! - Digital Microwave Sensor (SEN0192) - Mar2016

This sensor applies the Doppler effect to detect moving objects using microwaves. It differs from the method used by a regular infrared (IR) sensor as microwave is sensitive to a variety of objects, and its sensor readings will not be affected by the ambient temperature.

Digital Microwave Sensor is widely used in industrial, transportation and civil applications such as measuring vehicle speed, liquid levels, automatic door motion detection, automatic washing, production line material detection and car reversing sensors etc.
