🔧 How It Works
- The Ultrasonic Sensor measures the water level.
- The OLED Display shows the water level percentage.
- The Relay Module turns the pump ON when water level drops below 20%.
- The Relay Module turns the pump OFF when level is above 80%.
- The Buzzer alerts when the water level is too low (< 20%) or too high (> 90%).
