Hands are often contaminated with microbes and viruses that enter the body that can cause disease. With the spread of the corona virus increasingly widespread in various countries including Indonesia, prevention is needed. Thus, it is necessary to have an automatic hand washing device consisting of a water faucet, a soap faucet, and a hand sanitizer faucet. Manufacture of hand washing faucets with water output based on hand distance, soap and hand sanitizer measures automatically, so that they can be used easily, efficiently and practically. The method used in the design of this tool uses Arduino Uno R3 as a data processor, 3 optical proximity sensors are used to detect hand objects, soap, and hand sanitizer that work at a voltage of 4.92 volts as input and output relay to turn on the DC pump on this tool. removing or spraying liquid in the tube at a voltage of 4.92 volts. The results of the running test are expected, the proximity sensor reads a hand object at a distance of 10 cm to 20 cm, while the amount of liquid laundry soap is issued 1.8 ml and hand sanitizer is 2.8 ml.
