DEVELOPMENT OF A HANDS FREE URINAL FLUSHING SYSTEM

Abstract: In this paper an automatic urinal flushing system that ensures hands free flushing and conservation of water is proposed. Use is made of a delta DVP-I4SS2 programmable logic controller (PLC), limit switch and a solenoid valve to achieve the hardware design. A limit switch is actuated the moment a user steps on a standing pad placed at the front of the urinal thereby turning on the PLC input. The PLC uses this information to give an output command to actuate a solenoid valve to flush the urinal. Ladder control program was developed for the hardware control using WPLSoft software. Programming and testing of control program with the proposed system suggested that the system can be easily implemented at public places, banks, schools, restaurants and bus stop terminals at an estimated cost of US $ 202.
