红外线技术在工农业生产、通信技术、家用电器等多种领域中得到了广泛的应用,特别是在日常生活中的应用,更加受到了人们的瞩目。本文主要采用了红外线控制开关来控制水龙头。当有人洗手或用水时,接近水龙头的手或盛水容器将红外线反射回去一部分,被光敏晶体管接收并转换成相同频率的电信号,经过一系列的放大、解调、整形、比较后,得到合适的控制电压,控制电子开关"闭合",使电磁水阀通电自动开阀放水。当手或盛水容器离开水龙头时,光敏晶体管失去红外脉冲信号,电路又恢复到平时的待机状态。红外自动水龙头电路是由红外脉冲调制发射器、红外接收、译码电路、单稳态触发器、光电隔离器等组成。

Infrared technology in the industrial and agricultural production, communication technology, home appliances and many other areas have a wide range of applications, especially applications in everyday life, and more subject to people's attention. In this paper, uses an infrared control switch to control the faucet. When someone hands or water, up to tap the hand or containers that hold water back part of the infrared reflectivity has been received and converted into a photosensitive transistor the same frequency of the electrical signal, through a series of amplification, demodulation, shaping, compare, got the right The control voltage to control the electronic switch "closed" so that the electromagnetic valve power automatically turn on the water valve to open. When the hand or containers that hold water from the tap, the photosensitive transistor lose infrared pulse signal, the circuit has returned to the usual standby. Infrared automatic faucet circuit is modulated by the infrared pulse transmitter, infrared receiver, decoding circuits, one-shot flip-flop, optical isolators so on.
