Hands Free Corona Virus Fighter

Viruses such as COVID-19 are transferrable through touch and contact. There are WHO guidelines to regularly wash hands with soap or sanitize hands regularly to reduce the risk of infection. Dispensing of sanitizer and liquid soap from bottle and storage would require manual intervention. In this paper we propose a novel design of touch-less sanitizer machine [1] and touch-less soap dispenser machine [1] to reduce the risk due to contact. The system can sense the proximity with the help of infrared sensor and sends signal to the microcontroller. The controller processes the sensor data & actuates the pump and the solenoid valve. The sanitizer liquid dispenses through mist nozzle. The devices like mobile phones, electronic car keys, TV and AC remotes, paper currencies etc. cannot be washed with soap nor can be sanitized. In this paper we propose a novel design of touch-less mobile controlled UVC [2] disinfecting chamber to disinfect such liquid sensitive devices from corona virus using UVC radiation in closed chamber.
