It’s relatively easy to detect motion with a PIR sensor connected to your Raspberry pi’s GPIO.
This is merely an overview of how to write the python script. For more details on how to connect the sensor, read this.
When you have Python V2 you can follow this, check with python -V.
sudo apt-get update sudo apt-get install python-gpiozero python-pkg-resources python-dev
Now that you have all dependencies you can create a python script like:
#!/usr/bin/python from gpiozero import MotionSensor pir = MotionSensor(4) while True: if pir.motion_detected: print("Motion detected!")
Or you could just print if there is motion once:
#!/usr/bin/python from gpiozero import MotionSensor pir = MotionSensor(4) print pir.motion_detected
Now make the script executable:
chmod +x script.py
Now you can execute the script:
