Abstract

Abstract: The use of tap water on campus toilets is often problematic due to careless user. The water faucet on campus toilets is often left open, and this leads to wasteful and inefficient use of water. The purpose of this research is as a solution to save and control water usage on campus toilets with automatic faucet so that water usage can be used only when they are necessary or needed. Control of water usage on campus toilets using fluid mechanics and physics kinematics method by using solenoid valve as a valve to open and close the flow of water and flow liquid meter to calculate the water discharge data through it. While, PIR sensor that serve to detect the presence of humans in the toilets so that the solenoid valve can open and let the water flows. While Arduino UNO as microcontroller and Wi-Fi shield used to deliver the water discharge data to application that had been built. The test results show that the method used can work with stable to control water supply on campus toilets with the distance no more than 3 m and large number of users will not affect the performance of the sensor or system built.
