How to Make Automatic Water Level Controller

Introduction

Water is an essential resource that we must conserve. We should be careful about how much water we are using and make sure it is not being wasted. One of the major reasons for water wastage is overfilling of tanks, which is why it is crucial to have a water level controller that can monitor the level of water in the tanks. In this article, we will show you how to make an automatic water level controller using ESP32 and 16×2 LCD Display.

This is an excellent project for those who want to save water and money on their water bills. The ESP32 is a powerful microcontroller that allows us to monitor the water level in real-time and control the water pump automatically.

Explanation of Automatic Water Level Controller ESP32

Step by Step Procedure:

Connect the Ultrasonic sensor to the ESP32. The Ultrasonic sensor is responsible for measuring the water level in the tank. Connect the VCC and GND pins of the Ultrasonic sensor to the VCC and GND pins of the ESP32.
Connect the 16×2 LCD Display to the ESP32. The LCD Display is responsible for displaying the water level and the status of the water pump. Connect the VCC and GND pins of the LCD Display to the VCC and GND pins of the ESP32.
Connect the water pump to the ESP32. The water pump is responsible for filling the tank with water automatically when the water level is low. Connect the ground wire of the water pump to the GND pin of the ESP32 and the positive wire of the water pump to GPIO 16 of the ESP32.
Write the code for the ESP32 link of which is provided above. The code will read the water level from the Ultrasonic sensor and display it on the LCD Display. When the water level is low, the water pump will be turned on automatically, and when the tank is full, the water pump will be turned off.
Upload the code to the ESP32 and test the project.

Conclusion

In conclusion, the automatic water level controller using ESP32 and 16×2 LCD Display is an excellent project for those who want to save water and money on their water bills. This project is easy to make, and the materials required for the project are readily available. The ESP32 microcontroller is powerful and reliable, making it ideal for this project. With this project, you can monitor the water level in real-time, and the water pump will be turned on and off automatically, preventing overfilling of tanks. This project will not only help you save water and money but also promote water conservation.
