Open Arduino IDE and copy the following sketch in a new file and save it. Short microwaves serve in sensing applications, especially in radars, alarm systems, and human body detection.Īrduino Code: Motion Detection with RCWL-0516 Sensor Module Microwaves are electromagnetic waves with VHF/UHF bands used for communication purposes. Distance sensors are employed to measure the distance of the target by sending high frequencies. RCWL-0516 uses a doppler effect technique to sense moving objects. RCWL-0516 is a microwave radar sensor created to replace passive infrared motion sensors that utilize infrared light emitted by a moving person. RCWL-0516 Microwave Distance Sensor Module RCWL-0516 Microwave Radar Sensor Module with ESP32.RCWL-0516 Microwave Radar Sensor Module with ESP8266 NodeMCU.We have similar guide with ESP32 and ESP8266 NodeMCU: We will discuss the components of RCWL-0516 sensor module, pinout, configuration, features, specifications, interfacing, 2D model, and applications. In this user guide we will learn to interface RCWL-0516 microwave radar sensor module with Arduino and program it for motion detection.
