hi all,
I need help how to interface an ac motion sensor to PIC, the ac motion sensor I have is consist of three wires two for power and the last for switching to phase power when motion detected .
how I can detect this signal to PIC ?

Part number of the motion sensor?
Did you search the forum?

The easiest would be to use an optocoupler; you could drive the opto LED thru' a resistor connected to the switched output of the motion sensor, and the isolated output could then drive the PIC.

thanks, if one have schematic show the connection for ac sensors with PIC
