TechDepot Egypt's Description

Description

Mini PIR Motion Sensor is basically made of a tiny pyroelectric sensor, which can detect levels of infrared radiation. Everything emits some low level radiation, and the hotter something is, the more radiation is emitted. The sensor in a motion detector is actually split in two halves. The reason for that is that we are looking to detect motion (change) not average IR levels. The two halves are wired up so that they cancel each other out. If one half sees more or less IR radiation than the other, the output will swing high or low.

Mini PIR Motion Sensor Specifications

  • Operating Voltage Range: DC4.5-20V
  • Static current: <60uA
  • Output level: High 3.3V / Low 0V
  • Trigger: repeatable trigger (default)
  • Delay time: 8S + -30%
  • PCB Dimensions: 10 * 23mm
  • Induction angle: <100 degree cone angle
  • Induction distance: 3 meters
  • Working temperature: -20 – +80 degrees

Connection

Arduino +5v –> Sensor (+) Arduino GND –> Sensor (-) Arduino Digital Pin for example 4 –> Sensor (O) (in the Middle)

Code

void setup(){ Serial.begin(9600); pinMode(4,INPUT); digitalWrite(4,LOW);}void loop(){if(digitalRead(4)==HIGH){ Serial.println("Movement detected.");}else{ Serial.println("Nothing.");} delay(1000);}
