sounds like a good start, what exactly are you asking for?

I try to connect 4 pir sensors to the pic to detect the presence of human...

If any sensor output is high,it mean someone in room and currosponding fan should on...

When man leaves the room,the sensor output become zero and fan should off automatically...
I try to do this without any timer circuit.....

Presumably you are aware that PIR react to MOVEMENT?, if you stand still it will detect the room as empty.
