Human Presence Radar Sensor - Range 7m

The RCWL-0516 is a microwave radar sensor module used for motion detection. The range of the module depends on various factors such as the sensitivity settings, the power supply voltage, and the object being detected. Generally, the range of the RCWL-0516 module is up to 7 meters (23 feet) with a detection angle of 360 degrees. However, the range can be reduced or increased by adjusting the sensitivity potentiometer located on the module. It will continuously output the high level TTL signal when there is motion.

Arduino Code for RCWL-0516

    int sensorPin = 2; // define input pin for sensor
    int ledPin = 13; // define output pin for LED

    void setup() {
      pinMode(sensorPin, INPUT); // set sensor pin as input
      pinMode(ledPin, OUTPUT); // set LED pin as output
      Serial.begin(9600); // initialize serial communication
    }

    void loop() {
      int sensorValue = digitalRead(sensorPin); // read sensor value
      if (sensorValue == HIGH) { // if motion is detected
        digitalWrite(ledPin, HIGH); // turn on LED
        Serial.println("Motion Detected!"); // print message to serial monitor
      } else {
        digitalWrite(ledPin, LOW); // turn off LED
      }
    }
