5. Why Monitor Water Levels? Prevent Issues Avoid overflow, leakage, and unexpected water shortages. Diverse Applications From home tanks and agriculture to flood alerts and swimming pools . ESP32's Role A low-cost, Wi-Fi enabled microcontroller, perfect for IoT water monitoring. Efficient Management Helps plan water usage effectively, especially in areas with limited supply.

6. TYPES OF WATER LEVEL SENSOR

7. BLOCK DIAGRAM OF ESP32 SENSOR

8. WORKING PRINCIPLE Water rises in the tank. Low sensor triggers → Green LED ON. Medium sensor triggers → Yellow LED ON. High sensor triggers → Red LED ON + Buzzer ON. Provides visual and audible alerts for tank status Connect sensors to digital GPIO pins of ESP32: Low → GPIO32 High → GPIO25 Medium → GPIO33 LEDs connected with 220Ω resistor to ESP32 GPIO pins. Buzzer connected to another GPIO pin for high-level alarm

9. ESP32 MICRO-CONTROLLER The ESP32 is a low-cost, low-power microcontroller with integrated Wi-Fi and Bluetooth. It is widely used in IoT (Internet of Things), automation, robotics, and embedded systems because of its powerful features.

10. ULTRASONIC SENSOR The Ultrasonic Water Sensor is a non-contact water level sensor that uses ultrasonic waves to measure the level of water in a tank, reservoir, or container . Unlike simple conductivity-based sensors, it doesn’t touch the water, making it more reliable and safe.

11. LED - DISPLAY An LED Display is a screen or panel that uses Light Emitting Diodes (LEDs) to display numbers, characters, symbols, or graphics . It is widely used with microcontrollers like ESP32, Arduino for indication and display purposes.
