PIR Sensor

Cheap PIR sensor from a local store

This cheap PIR sensor with LED light is an eye catcher for hacks at only 150 Philippine peso. A generic PIR based on the LP0001 PIR controller chip and can readily be used for projects. The circuit reveals a basic circuit based on the datasheet of the controller chip, the signal from the output pin can be directly connected to any microcontroller. This model has a switch labelled on, off and auto. make sure that the switch is set to auto or you could bypass the switch by replacing it with a jumper.
