Hello, I replace a PIR Motion Sensor according to the 6 steps in my phone.
I followed the schema reported of product introduction and steps in the posted url, but it does not work, it gives me values not consistent with the movements.
I am not so good in electronics, so I don’t know how to proceed.
The signal produced by the PIR is 0V when there is no motion, and 12V when some motion is sensed.
I also tried to connect the signal produced with a series of two resistors: 14Kohm and 10Kohm. And then to the ground. In this way, the potential difference between the 10Kohm resistor and the ground should be 5 volts when some motion is sensed. Anyway it does not work!
Can anyone help me?
