Smart Faucet with Automatic Door Control System

COVID-19 is an infectious disease that causes serious pandemic. There are many means to contradict the outspread of the microbe and one such way is to sterilize the hands by washing with soap for 20 seconds. Despite washing hands regularly, there is a tendency to touch the contaminated surface in the tap and door handles. In order to make the hands contamination-free before entering the premise, a solution that a person will be allowed to enter only after hand washing has been implemented. Having an automatic faucet and door which will be controlled using the micro controller Arduino Nano wherein various sensors like IR sensor and other devices like servo motor, relay module and LCD display will be interfaced with the micro controller has been proposed. An IR sensor will be placed at the door that senses whether the person has washed his/her hands or not and grant access for the entry. Another IR sensor will be placed at the faucet and it will sense the person’s hand and control the water flow accordingly. The proposed system will ensure whether people have washed their hands before entering their premises and grant access accordingly.
