The proposed system was built because of unhealthy pattern of drying of hands after washing in various restaurants and places of food selling and the rate of disease transmission such as corona virus and Ebola has prompted the need for this project. The hand dryer consists of Light Department Resistor (LDR) and 555 timer IC. The 555 timer IC is work as a monostable mode that it drives with the 5 V relay. Laser light falls on the LDR, the hand drying system remains OFF state and when the laser light is blocked by the hand from falling on the LDR, the hand drying system remains ON state. In the other words, the light from the laser module is cut off by the hand then the dryer is activated.
