Abstract: The infrared technology in the industrial and agricultural production, communication technology, and many other areas of household appliances has been widely used, especially in daily life applications, more people's attention has been. In this paper, a reflective infrared sensors to control the tap. When people wash their hands or water when the hands close to the tap or water containers will go back to a part of infra-red reflection, the infrared receiver to receive control and converted into corresponding voltage signal, through a series of pale pinkish purple, zoom, identify, after decoding, so that LM567 output low level, but also by the RP, the driver transistor turn-on, so that the relay pull-in, automatic power control valve of electromagnetic valve to open water. When the vessel left hand or tap water, the infrared receiver lost control infrared signal, the circuit has returned to normal standby mode. Infrared automatic faucet control circuit is a
