Description

It uses Doppler radar technology, with auto-sensing capabilities to control other product, sensor with high sensitivity, reliability, wide angle sensor,Wide supply voltage range . It is widely used in lighting situations,anti-theft alarm situations.

  • Working voltage: 3.3-20VDC
  • Standby quiescent current: <3mA
  • Transmit power: <2mW;
  • The working environment temperature: -20℃~+80℃;
  • The output signal: TTL level; high is 3.3V and Low is 0V
  • Detection angle: 360°(spherical)
  • Detection range: 6-8 meters

Note : By installing the  Photoresistor (LDR), the module will deactivate if there is no light and works only in dark.

PINOUT

Getting started with 5.8GHZ Microwave Radar Sensor

In this project you’re going to create a simple circuit with an Arduino and Microwave radar sensor that can detect movement. An LED will light up when movement is detected.

Parts required

Connecting the Hardware

Arduino                             Microwave Radar Sensor

D2                                          0

VCC                                        VCC

GND                                        GND

CODES

Upload the following code

int led = 13; // the pin that the LED is atteched to
int sensor = 2; // the pin that the sensor is atteched to
int state = LOW; // by default, no motion detected
int val = 0; // variable to store the sensor status (value)

void setup() {
pinMode(led, OUTPUT); // initalize LED as an output
pinMode(sensor, INPUT); // initialize sensor as an input
Serial.begin(9600); // initialize serial
}

void loop(){
val = digitalRead(sensor); // read sensor value
if (val == HIGH) { // check if the sensor is HIGH
digitalWrite(led, HIGH); // turn LED ON
delay(100); // delay 100 milliseconds

if (state == LOW) {
Serial.println(“Motion detected!”);
state = HIGH; // update variable state to HIGH
}
}
else {
digitalWrite(led, LOW); // turn LED OFF
delay(200); // delay 200 milliseconds

if (state == HIGH){
Serial.println(“Motion stopped!”);
state = LOW; // update variable state to LOW
}
}
}

NOTE: IF you  get stray ‘223’ errors The problem is with your  and  characters. Replace them with ordinary quotes, ", and you should be fine.
