DAM CONTROLLER TECHNOLOGY (DCOTECH) By : Mazratul Firdaus Mohd Zin,  Fatimah Nur Binti Mohd Redzwan, Farid Zuhri Kamal, Hazwani Zawawi, Irfan Arif Mohd Zaher OBJECTIVES          To prevent floods and provide a good reservoir in residential areas.       To warn the residents to be more prepared when flood happens. Figure 1 : The PCB layout of DCOTech       Dam Controller Technology (DCOTech) is designed to detect and control the water level in a  roof-mounted tank or any other reservoir at residential areas. This system monitors the water  level of the tank and automatically switches OFF of the motor when tank is in EMPTY state.                                                                                                     METHODOLOGY Figure 2 : The flowchart of DCOTech        The motor is switched ON when the tank is in FULL state. More specifically, a microcontroller is used for water level sensing and controlling maneuver for the DCOTech. The microcontroller detects and senses the water level at three level which are LO, AVERAGE, and HIGH. Water level management approach could help reducing the water overflow and possibility of flash floods. In this project, an embedded automatic water level controller has been implemented to control the water level of water reservoirs and tank. Arduino UNO is used in the project as the controller to switch ON/OFF the motor accordingly and the output is presented with LEDs. The GREEN LED lights up if the water level is at LOW level, YELLOW LED lights up when the water is at AVERAGE level and RED LED lights up when the water level is at HIGH LEVEL.
