Motion Sensor Problem

Question

Hello, I install a PIR Motion Sensor according to this step.
I followed the schema reported 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?

Hello,

I think this is not the right forum for getting help concerning your question... Here we are focused on GUI development with Embedded Wizard. Hardware aspects are only discussed in context of graphics acceleration, displays and touch devices.

Maybe you can find some help in hardware forums.

Best regards,

Manfred.
