See as the figure, the circuit consists of the heat releasing infrared detection module, relay control light circuit, curses making circuit and AC step-down rectifier circuit, etc. When there are people coming in the chapel, the internal lighting lamp is glowing automatically and the Buddhist scriptures sound is generated; when the people are out, the light and sound are both gone.
