UPDATE: Replaced my PIR-Sensor with a Doppler Microwave Sensor.

@bachoo786 First re-check if the sensor is cabled correctly to the GPIO as described in my tutorial. Further check if the resistor is soldered correctly to the sensor. Maybe there is a “cold soldering joint”. Sounds trivial, but the devil is a squirrel (old german saying )
Then, extend the detection range to the max, to check if the sensor is generally OK (200 Ohms) and re-run @cowboysdude script. If this works, then reduce the resistor step by step until you reach the desired detection range. Theoretically 80 Ohms should provide a range of 40-50 cm, but from my experience this may vary strongly as the resistor value does not correspond linearly to the detection range.

@Fozi ok will do thanks.

@Fozi Hi

I am on raspberry pi 4 and I think wiringPi does not work with it as the guy has stopped developing it any further. Is there any other way I could make this work?

Thanks.

@bachoo786 there exist alternative libs like piGPIO or GPIOzero, but I have no experience with them. Why not try MMM-PIR-Sensor? It is easy to install and to configure and works out of the box with the RCWL-0516.

[bachoo786]

@Fozi nope none of them worked for me very surprising.

@bachoo786 Same for me. Couldn’t get neither MMM-PIR nor MMM-PIR-Sensor to work, but on a Raspi3B+

Hmmm…that’s strange.
Here is my config for MMM-Pir-Sensor I use:

//----------------------------------------------------------------------------------------
{
        module: 'MMM-PIR-Sensor',
        config: {
        sensorPin: 4,
        powerSavingDelay: 150, // (seconds) how long the monitor will be turned on
        
        }
},
//----------------------------------------------------------------------------------------

And this is the wiring of the sensor with the GPIO, which corresponds to the above config. ‘sensorPin: 4’ corresponds to GPIO_4 (brown cable)

@Fozi The odd thing is that I didn’t even get the module installed properly. However, just tried again and it seems to work now. Maybe because of MM v 2.10.0. I don’t know…

[Fozi]

@lavolp3 great!

More or less the same problem for me…
I’m using a velleman VMA314 connected to GPIO pin 11 (BCM GPIO 17) and module MMM-PIR-Sensor.
I’ve updated wiringPi for Pi 4 (wiringPi updated to 2.52 for the Raspberry Pi 4B)
I see that state changes using “gpio readall” but nothing happens…or to start with, connected screen does not even turn off after time set in config:

		{
			module: 'MMM-PIR-Sensor',
			config: {
			// See 'Configuration options' for more information.
				sensorPin: 17, // The pin (BCM numbering, NOT pin number itself) your PIR-sensor is connected to.
				powerSaving: true, // Should the monitor be turned off if no user is present? (via HDMI or relay)
				powerSavingDelay: 5, // Additional software side delay (in seconds) before the monitor will be turned off.
				powerSavingNotification: true, // To display a notification before to switch screen off
				powerSavingMessage: "Skärmen stängs av på grund av inaktivitet..." // Message notification to display before to switch screen off
				
			}
		},
