医院、宾馆、饭店、公园以及公共厕所等场所的水龙头,由于使用的人多,很容易传染疾病,因此这些场所的水龙头最好是无旋钮和自动的。本文介绍一种红外自动水龙头,这种水龙头将红外发射部件和接收部件装配在一起,具有简单实用、灵敏可靠、抗干扰性好、可在强光下工作等特点,既可达到节水的目的,又清洁卫生,因此非常适合在上述环境中使用。这种红外自动水龙头的工作原理如右图所示。IC_1时基电路输出频率为10KHz、占空 Faucets in places such as hospitals, hotels, restaurants, parks and public toilets are prone to disease due to the large number of people being used, so the faucets in these locations are preferably knobless and automatic. This article describes an infrared automatic faucet, the faucet infrared emission components and receiver components together, with a simple and practical, sensitive and reliable, good anti-interference, can work under strong light and so on, can achieve the purpose of saving water , But also clean and hygienic, it is very suitable for use in the above environment. This infrared automatic faucet works as shown on the right. IC_1 time base circuit output frequency is 10KHz, duty cycle
