It includes the head of pyroelectric infrared sensor, infrared sensor application specific integrated circuit and the light control circuit composed of external components, and relay control circuit, music voice circui and AC rectifier buck circuit. When there is pedestrian access to the detection area of pyroelectric infrared sensor (PIR). PIR detects the infrared signal radiated by human body. The signal will be converted to low frequency (0.5 ~ 9Hz) signals. The signal will be added to the input op amp (14 feet) of BISS0001. The signal is amplified, filtered and information processed. Then the signal at output terminal 2 feet output a certain delay of the high output control signals. Add the control signal to VT1 relay control circuit to pull in the K1, and its contacts K1-1 closes, the electromagnetic valve W gets water sprays.
