= Description =
A PIR Sensor can detect motion, it is also called motion sensor. It detect moveing people or animals. PIR stands for passive infrared. Here we use the SR602.

It has 3 connectors:
* - connected to GND
* + connected to 3.3V
* Out - digital output is 1 if motion is detected

This one is the HC-SR501 sensor and it should be connected to 5V, GND and a digital Pin.

= How to control it in MicroPython =
Reading the value and printing it to the console
<syntaxhighlight lang="python" line='line'>
#Example usage for ESP32
from machine import Pin
from time import sleep
# digital input on pin 26
pir = Pin(26, Pin.IN, Pin.PULL_UP) # enable internal pull-up resistor

while True:
pirVal = pir.value()
print(pirVal)
sleep(1)
</syntaxhighlight>
