1、 光电水龙头光电水龙头 摘要摘要: 本着节能减排的目的, 我设计了利用红外发射与接收电路 设计自动水龙头的原理及设计方案。传统的公共水龙头、卫生间的供 水等施,使用起来不是特别方便,而且很浪费水资源。不仅可以节约 用水,而且外形美观,使用起来也很方便。红外线控制自动水龙头由 红外发射电路、 红外接收放大电路、 控制电路、 电磁阀、 电源等组成。 当人或事物靠近时,自动产生控制信号,继电器动作,使电磁阀得电 吸合从而自动打开水源;反之则自动关闭水源。 关键词关键词:红外线传感器;555 定时电路;自动控制 Abstract This paper describes the use of infr
