Make a PIR Movement Detector 3.3V compatible
This PIR movement detector runs on 4.5V-20V unfortunately I had only 3.3V available from the esp32
The cool thing is, it has a voltage regulator and a diode (that eats some volts) on board, that converts this 4.5-20V to a 3V voltage, so just remove it and use 3V Vcc š

And replace with lead:
