Water Level Detector Project Using Arduino - Water Level Sensor - LCD I2C - RGB LED - Buzzer

💧 Arduino Water Level Detector using Water Sensor, I2C LCD, RGB LED & Buzzer In this project, I built a Water Level Detection and Monitoring System using an Arduino Uno, a water level sensor, a 16×2 I2C LCD display, an RGB LED, and a buzzer. The water level sensor continuously measures the amount of water and sends the data to the Arduino. Based on the sensor reading, the system classifies the water level into three stages: LOW, MEDIUM, and HIGH. The current sensor value and water status are displayed on the LCD, while the RGB LED changes color and the buzzer provides audible alerts to indicate the water level. Water Level Indications: 🔵 Blue – LOW water level (slow beep) 🟢 Green – MEDIUM water level (short beep) 🔴 Red – HIGH water level (fast beep) This project demonstrates analog sensor reading, sensor calibration, threshold-based decision making, LCD interfacing via I2C, RGB LED control using PWM, and buzzer integration with Arduino.
