Hand Design and Simulation. By the infrared sensor module, the microcontroller module and digital display module composed of three parts. The design of the infrared sensor signal into 51 single-chip, single-chip control by triggering the relay, start drying hands. This report describes in detail the basic design ideas and principles of this project, and accordingly with the necessary schematics and circuit modules.
