Usually when using Public toilets we often doubt about the hygenie of seat cover and germs can be easily transmitted
through hands.I thought of making an hands free toilet seat cover as final project in my fab academy course.
Features.
1. Automatic cover closing and opening.
2. UV C light based Disinfection system.
Main Components
1. Seat cover ( Acrylic or Plywood sheets)
2. Ultra Violet(UV C) light system
3. Sensors (PIR sensor and Ultrasonic sensor)
4. Embedded Microcontroller(PCB).
5. Power unit( servo motor, gears etc ) for opening and closing
Some skecting..
Construction Plan
1. Toilet seats are readily available in the market. But I intend to design and fabricate a seat cover in the lab. Either I will
go with an acrylic sheet/plywood sheet and laser cut it to get the desired shape or mill it usinga CNC Machine.
2. UV LED strips or lambs will be used for disinfecting the toilet after the usage.
3. PIR sensor along with ultrasonic sensor will be used for detecting the presence of human beings and the signal will be used
for opening and closing of seat cover.
4. Embedded microcontrollers will be programmed and interfaced for controlling the tasks.
5. Servo motors will be used for opening and closing the lid. I intend to give a counter weight on the lid for reducing load on
the servo motor.
