Abstract

Nowadays, there are almost of the entire place example at restaurants, public houses, offices/industry, school, colleges and universities have the hand washing tool. The functions of this tool are to washing and drying the hands. But normally this tools operating by semi automatic or manual. To give this tool can more systematic and particular „an automatic hand washer and drying machine‟ for automatically washing and drying the hands is proposed. This project will design to combine three functions in one device which is the soap, water and dryer. The project consists of the microcontroller chip, an Infra-Red (IR) sensor and any other device. The main component that must be used to make sure an automatic hand washing and drying machine operating for automatically is microcontroller chip and the microcontroller chip that be used is PIC16F877A. This microcontroller used to control the whole machine which is water, soap and dryer. The IR sensor consists of an IR transmitter sensor and an IR detector sensor. The IR transmitter sensor will continuously emit an IR wave, forming a straight light from the IR transmitter to the IR detector. When the IR wave between IR transmitter sensor and IR detector sensor is interrupted by user hands, a signal will be send to the PIC 16F877A. Then the PIC 16F877A will analyze the signal and the machine will operated whether produce water, soap or drying process will happen.
