PIR Senor Test

shgmongohh

Hi,

I have some problems to install the pir sensor to send the monitior to sleep.

I don´t know, if my sensor is working correct. Has anybody a tutorial, how to connect the pir right and to test the function?

I think I connect everything right, but it doesn´t work.

I thought the same for a long time using the because I didnt have a breadboard. I went with the PIR Setup on the raspberry pi website. Managed to use this code to see that it works. You will need gpiozero to run it. Open Python 3. File > New. Paste this code in.

from gpiozero import MotionSensor
import os

pir = MotionSensor(4) #4 is the Pin?
while True:
  if pir.wait_for_motion(timeout=10*60): #10 * 60 Seconds
        os.system("/opt/vc/bin/tvservice -p")
  else:
     os.system("/opt/vc/bin/tvservice -o")

You can if you want edit
os.system("/opt/vc/bin/tvservice -p")
to
print("Motion Detected")
to test if your PIR Sensor is working ok. After changing it, save it and press Ctrl + F5 to run the code. It will then spam up with motion detect or undetected depending on what you’ve changed.
