I have just bought an PIR Motion Sensor but I am not sure that it works.
It has tree pins as the image says, I put 12 v in the red pin, put the middle to ground and it is supossed I have to get a voltage in the alarm pin.
I close the circuit with a resistor in the alarm pin and then the resistor to ground but when I measure voltage in the last pin or in the resitor 0 V is obtained, also covering the sensor.
is the motion sensor broken?
could anybody help me? Thank you in advance.
No public wish lists :(
