Pyroelectric sensor light switches body

Figure shows the circuit which helps to control or arrange the lighting glow. P228 is an effective PIR sensor,which is an excellent performance human detector. When any person comes near the sensor, the sensor detects it and triggers the IC YX7603, which makes the lamp to glow. It can be used as automatic light circuit, mainly for energy saving purposes, for security of room or home, as a light alarm, for all security purposes.
