Development of an Automatic Hand Cleansing Station With Visitor Counter For Crowd Control During Covid-19 Pandemic Era

In the modern world, there is perpetual requirement for automated device that would be designed in other to control. Crowds gathering ,which is one of major sources of transmission of CoViD-19 deadly disease as such that a proactive measures have to be put in place and focused on by reducing the number of people at a work space per time. CoViD-19 visitor counter counts the number of people entering a venue considering its capacity in order to avoid congestion. Proper hygiene is also another way to reduce the transmission of the disease among people as advised by the World Health Organization (WHO). This paper aims to control crowd in a room by designing and deploying an automatic hand-cleaning station placed at the room entrance to track movement, enhance hygiene through hand washing and to relatively reduce the environmental landfill caused by improper disposal of paper towels and the subsequent Carbon dioxide emission from burning. The visitor counter of the hand-cleaning station is designed in two parts: the proximity sensor and counter display. The sensor would detect when someone places their hand under the soap dispenser and then initiate the process of automatically dispensing tap water for about 25-30secs before allowing the use of a hand dryer and sterilizer. Thereafter, the room’s door will be opened for a period of 10secs to allow access and an increment in the number of visitors being displayed on the LCD. The lock opens when a button is pressed from the inside while going out so that the door can open, and a decrement on the visitor counter is recorded. The device can be deployed for crowd control with fully practiced hand hygiene to curb the spread of CoViD-19 transmission within the citizenries.
