Sensitive, low consumption, stable performance, long life, energy saving and so on. Here are sound, light control automatically delay saving switch, combines sound, light and time delay control, job security, power saving and extended lamp life. This design choice of acoustic sensors, photosensitive sensor etc as the design of the basic elements, with AT89C2051 microcomputer as the core, and adopting the serial A/D for sound signal collection, integrated sound, light and delay the control. This system its stable work, saving energy and can prolong the service life of the bulb. Photosensitive sensor, sonic sensor two sensors to unify mutually formed sonic, optical two control circuit. Article applied zero start-up technology, switch work in frequent switch to SCR. The system also joined the Watchdog circuit, in the process plays a role of anti-interference, greatly strengthened the system reliability and practicability.
