Design of Automatic Water Flood Control and Monitoring Systems in Reservoirs Based on Internet of Things (IoT)

Uncontrolled water level can make a reservoir overflow due to lack of information to the flood gate supervisor, this is due to the current flood gate control system. One of the developing fields of technology is the Internet of Things (IoT). The IoT on this prototype are used for real-time control and monitoring of water levels by using a web server as an interface. The components used consist of ESP 32 micro-controller, ultrasonic sensors for reading water level data and stepper motor actuators to control sluice gates with 3 water level conditions: low, medium, high. Analysis of the test from the reading of the IoT-based sensor produces a percentage error of 0% and time delay of sending data at a value of 2 seconds as shown by each experiment 20 times.
