and output switching signals. It can be applied to a variety of occasions to detect the movement of human
body. Conventional pyroelectric infrared sensors require body pyroelectric infrared detector, professional
chip, complex peripheral circuit, so the size is bigger, with complex circuit, and lower reliability. Now we
launch this new pyroelectric infrared motion sensor, specially designed for Arduino. It uses an integrated
digital body pyroelectric infrared sensor, has smaller size, higher reliability, lower power consumption
and simpler peripheral circuit.
Input Voltage: 3.3 ~ 5V, 6V Maximum
Working Current: 15uA
Working Temperature: -20 ~ 85
Output Voltage: High 3V, low 0V
Output Delay Time (High Level): About 2.3 to 3 Seconds
Detection angle: 100 °
Detection distance: 3~5 meters
Output Indicator LED (When output HIGH, it will be ON)
Pin limit current: 100mA
Size: 30*20mm
Sample Code:
byte sensorPin = 3;
byte indicator = 13;
void setup()
{
pinMode(sensorPin,INPUT);
pinMode(indicator,OUTPUT);
Serial.begin(9600);
}
void loop()
{
byte state = digitalRead(sensorPin);
digitalWrite(indicator,state);
if(state == 1)Serial.println(“Somebody is in this area!”);
else if(state == 0)Serial.println(“No one!”);
delay(500);
}
