A PIR Sensor can detect motion, it is also called motion sensor. It detect moveing people or animals. PIR stands for passive infrared.
It has 3 connectors:
- + connected to GND
- - connected to 3.3V
- Out - digital output is 1 if motion is detected
How to connect it electrically
How to control it in MicroPython
Reading the value and printing it to the console
#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)
