Build a Thief Detector using an Arduino UNO and a RCWL-0516 Microwave Proximity Sensor - Electronics Infoline
[ By Electronics Infoline Team ] ==================================== In this tutorial, we will talk about a motion detection system using the Doppler effect and microwave, and for this project, we are using RCWL-0516 motion detection module with Arduino UNO. if we talk about motion sensors then there is one more popular motion sensor called PIR HC-Sr501 and this sensor uses “Passive InfraRed” light waves technology to detect the motion. PIR sensor module is emitted by animals or humans mostly and those things that are warm or hot. RCWL-0516 unlike the PIR sensor, RCWL-0516 continuously sends microwaves around it and those waves reflect back. And if anything moves near the sensor range then that body makes a change in the waves and this frequency known as the “Doppler effect”. The Really Cool thing about this sensor is, it can detect moving objects through walls and other materials such as plastic, wood, which means we can simply hide this sensor behind the wall or we can even hi...
