Description :
Automatic flush system for sanitation in public toilets is designed and implemented using Microcontroller. In manual flush systems, the user presses a button, which opens a flush valve allowing mains – pressure water to flow into the bowl, or sometimes the user presses directly a flush lever. The valve contains an air-filled mechanism that closes it after a preset time. A Microcontroller based system using sensor technology; this automatic flush system is designed.Microcontrollerbased automatic flush system is given in figure 1 and 3. The Infra-Red transmitter LED andthe Infra-Red receiver modules are mountedside by side such that when the userapproaches the mechanism, the Infra-Red receivermodule receives the Infra-Red signals reflected off the person. A solenoidoperatedwater valve is used in the system.The AT89C2051 8-bitmicrocontroller with 2 kB of flashbasedprogram memory,128 bytes ofRAM, 15 input/output lines, two 16-bit timers/counters, on-chip oscillatorand clock circuitry is used for the implementation of the system. Another approach of this work is to save water.
