I would like to turn a 110v fan off for several minutes when motion detected. Is there something I can buy or would I need to make something? I'm a Auto painter by trade and know very little about electronics.
When you say module, i presume you are refring to a PIR sensor with a circuit. Just a PIR sensor
will not be sufficient. An circuitry will also be required to make the sensor work. Thus as i have seen, the module will have a tiny jumper which will activate the output for 1 second/ 2 seconds depending on the position of the jumper. There are other makes which doesnt have this facility. One such module is available from
parallax. Refer the given link. Cheers **broken link removed**
