PIR Sensor Module
KC7783 is a PYROELECTRIC sensor module which developed for human body detection. A PIR detector combined with a fresnel lens are mounted on a compact size PCB together with an analog IC, KC778B, and limited components to form the module. High level output of variable width is provided.

* PIR Detector
* Photocell for dusk/dawn
* Activate indoor or outdoor
or sound a chime to alert you when
someone approaches
* Outdoor dual floodlights (not included)
* RF 433.92MHz
This unique product takes you above and beyond the capabilities of similar looking devices. In addition to turning on dual floodlights when the detector picks up motion, the can turn on up to 10 modules in or around your home. Security and convenience applications for this product are endless. Can be turned on or off from other X10 controllers.
