Auto Tap Controller

Automatic IR Tap Controller

Automatic IR Tap Controller : Everybody is driven by the growing concern over germs in washroom surfaces. People are avoiding contact with anything in any bathroom away from home. So automatic taps and flushers can effectively reduce possible cross-contamination. Because of this fact increasing number of commercial, private, and public buildings are now installing automatic taps, flushers, cleaning systems, and other touch-free devices.
The Atmel ATMega8 is the most efficient high performance, low power 8-bit RISC microcontroller that offers the following main features used in this project.

Hardware Features
  • One 6 V Relays (5Amp) with expansion connector for NC/NO/COM.
  • Supply voltage : +12V, 600mA` from battery emulator.
  • Power ON Reset.
  • 2 Nos. 6 pin connector for stepper motor used in thermostatic mixing of water.
  • Expansion connector for supply of Motor.
  • Expansion connector for proximity sensor input.
Software Features
  • Hands free infrared proximity detection.
  • Manual override button.
  • Thermostatic mixture with adjustable temperature control.
  • Built in thermostatic control valve maintains temperature by adjusting the flow of each hot and cold supply. When water begins to get colder, the thermostatic valve will automatically reduce the flow of cold water to compensate. This is particularly useful in guarding against the possibility of scalding injuries.
  • Minimal power consumption.
  • Low Battery Indication.
This technique can be used in applications such as
  • Automatic Soap Dispenser.
  • Automatic Flushers.
  • Automatic Cleaning devices.
