with PIR motion sensor alarm system circuit http://www.geocities.com/archilochus57/images/sensch.gif

Because of the night light saver using AT89C2051 microcontroller,i need also the program coding for it. The system will be like this:

1. The night light will on on specific time (eg. 2200H till 0100H)

2. Then after the light is off, the PIR sensor will be operate and sense if any intruders movement in the room.

3. If there any movement happened, the PIR sensor will sense signal to the Microcontroller AT89C2051 and on the light plus sound the buzzer.

I relly need you guys help..
