PIR sensor pIC16f877
hi everyone , i want to ask on how to deal with PIR sensor...PIR sensor is basically a motion detector that detect motion...so in this case, i would like use that sensor to act as as input to my ceiling fan controller( using LM35 sensor)...
the problem is, this sensor only operate as the motion goes through. while in my project i would like to use it to detect the human that pass through the door which automatically turn on the entire ceiling fan controller....i wonder, as the human pass through the door like 5 meter away from the door...isn't the overall system will turn off? how to make it still operating??? i just want to turn it off (overall system) if the human leave the door/room....
easy to say, if someone entering the room overall system still on...if the someone leave the room the system will be off...
can anyone help me?
