<![CDATA[PIR Sensor + Raspi]]>Hi everyone!
I’ve got a doubt. I’ve been watching a few videos on youtube on how to connect the pir sensor to the raspi.
In every video, they use an arduino or a protoboard. Is this really necesary, or with the female-female cable, the PIR sensor and the raspi is enought?

Kind regards

{
module: 'MMM-PIR-Sensor',
    config: {
        sensorPIN: '18',
        powerSaving: 'true'
    }
},

(my module config)

Otherwise, this image show you which pins you have connected. If oyou have it set up the way PtrBld suggested, you change the code to 24.

Sorry, I’m pretty new in this, and I can’t get it easyly

You have 5v, Ground, then GPIO.

Keeping in mind for both this code and the module that you have the correct pin number.

How do I know in what pin are the 3 cables connected?

from gpiozero import MotionSensor

pir = MotionSensor(4)
while True:
    if pir.motion_detected:
        print("Motion detected!")

Keeping in mind for both this code and the module that you have the correct pin number.

Any idea why is not working?

Maybe you should calibrate your PIR sensor tuning. There are two little orange knobs where you can adjust the sensitivity of the sensor.

I have connected the cables as the picture you post. Any idea why is not working?

Following this guide worked beautifully.

you do not need to use an arduino or anything else. Just connect the Pir-Sensor to the raspberry pi like this:
