Abstract

The water level detector system is a straightforward method for detecting and indicating the amount of water in the water tank and other containers. The majority of households nowadays use pumps to store water in water tanks. However, no one can tell how much water is in the tank or when it will fill up. As a result, the tank will be empty, resulting in not knowing the condition of water in the water tank. A water level detector is a device that collects data on the water level in reservoirs or tanks in residences. Therefore, we can prevent water from being empty in the tanks by using the water level monitor. Besides that, all the connections between the power supply, the microcontroller and the switches are simple and straight forward to make the installation easy and fast. The system is designed to hook on the water tank with its water buoy customized to the height of the water tank, resulting in easy installation. The NodeMCU ESP8266 microcontroller serves as the project's brain, bridging the gap between all input and output devices. EEPROM in this project is used to store data in this system. The cycle for the switches to on and off at the water tank bouy will be read by the NodeMCU ESP8266 microcontroller. By using Arduino IDE software, the NodeMCU ESP8266 is programmed to read the level of water in the tank which is triggered by the switches and LED light will light up according to the level of the water. The water level will also be displayed in the Blynk application which shows the data based on the height of the water in a tank.
