AUTOMATIC DAM GATE CONTROL SYSTEM WITH CAUTION ALARM

Abstract

Water level in a dam needs to be maintained effectively to avoid complications. This is generally
performed manually which requires full time supervision by the operators & have fairly large staff complements.
Moreover, the quantity of water released is hardly ever correct resulting in wastage of water & it is impossible for a
man to precisely control the gates without the knowledge of exact water level and water inflow rate. The main
objective of this project is to develop a mechatronics based system, which will detect the level of water and estimate
the water inflow rate in a dam and thereby control the movement of gates automatically in a real-time basis which
offers more flexibility. This system consists of a set of sensors connected to AC/DC motor through a
microcontroller. This microcontroller operates the relay and switches the AC motor ON/OFF depending on the level
of water.. The water level and rate of inflow is detected based on the feedback from the sensors used. Based on this
data, the water level of dam gate can be automatically controlled using an AC motor. This project uses two power
supplies, one is regulated 5V for modules and other one for Arduino. 7805 three terminal voltage regulator is used
for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step
down transformer.
