The microwave sensor applies the Doppler effect to detect moving objects using microwaves. This differs from the method used by a regular infrared (IR) sensor as microwave is sensitive to a variety of objects that are microwave-reflective, and its sensor readings are not affected by the ambient temperature. This type of 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. In this application we are using Digital Microwave Sensor Module having frequency of operation 10.52 Ghz interfaced with Arduino UNO logic board. The sensor gives digital logic output. The microcontroller Atmega328 processes data from the sensor. It displays status on 16×2 LCD and activates buzzer if any motion is detected by sensor.
