Object motion detector circuit diagram


Posted on Feb 5, 2014

The heart of the motion detector movement detection circuit is motion detection chip IC1 (KC778B). The signal frequency from PIR sensor is low (0.1Hz ~ 10Hz) while the band is very wide, the chip will optimize it. The working voltage of KC778B is 4V ~ 15V, 78L05 requires 9V ~ 12V input voltage. The circuit has three sensitivity controllers. You can see a b..
