In this COVID-19 pandemic situation everything was closed in Bhopal, India during the lockdown except essential supplies and even the courier services were closed
1 / 3 • DUAL MODE TOUCHLESS MULTIPURPOSE HANDWASH POINT
To protect from COVID-19 we need to stay at home and follow social distancing when the unlock started. Also, we have to be very cautious in touching the surfaces and clean hands frequently with soap or alcohol based sanitiser.
In the public places, offices, shops if we need to clean our hands we need to touch soap dispenser, water tap for opening/closing. Still, the best method to clean Hand is cleaning with soap.
To protect people from touching the water tap or soap/sanitiser dispenser a solution is proposed ( See Demo Video Link) using material which are only available during lockdown such as water purifier solenoid valves, 24 V power supply unit of purifier unit and associated piping. The aluminium scrap and plastic sheets is used making enclosure. The enclosure is tough and designed for heavy duty and same design can be used by anyone. For hardware I have used ESP32, Ultrasonic sensor, Relay board and 5V power supply unit were available with me for learning the IOT.
Project is created by arranging resources during lockdown.
In this project :
1) I have provided multiple option of installation of the system as per user requirement i.e.
a) the dispenser can be placed on table or
b) mounted on wall over wash basin/sink
The user need water supply ( if soap+ water option is used) and 220 VAC power point.
2), I have designed the system for dual mode, i.e. if water supply is available it can be used as soap+ water dispenser and if water supply is not available and need to put immediately for use by changing to Soap + water mode to
MODE 1 -SANITIZER MODE, 0-SOAP+ WATER MODE
sanitiser mode through a switch and it can be used as sanitiser dispenser
easily by filling the soap container with sanitiser,
