      Hi !

      I want to put a pir sensor but I don’t know which one to choose and if it will be compatible with my monitor.
      The monitor is connected in DVI with a DVI / HDMI adapter.
      And if you have a good tutorial for me please ^^

      Thank you !

        The PIR sensor does not depend on your screen or the connection to the screen.
        The sensor comes with three pins:

        1. power supply
        2. ground
        3. data

        If the sensor detects a heat change (e.g. a person is coming closer to the sensor) it triggers the data port to say “I noticed something”. Based on this detection you can tell your pi/your script to do whatever you want, for example disable the HDMI port.

        This tutorial is for arduino, but the technical part should be of help: https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor/overview

          Thank you

          There is a way to simulate the operation of the sensor to see the result on my monitor ?

            What do you want to simulate? The behaviour before you buy a sensor? Or check the output/detection before actually disabling the screen?

              Yes I want to simulate the behaviour before buying the sensor
