IoT Based Water Pump Controller using ESP32 Blynk & float sensor

In this IoT internet of things project, I have shown how to make the IoT based water pump controller using ESP32 Blynk and float sensor. This water level monitoring system will also check the water level in both the overhead tank and underground water tank and accordingly control the water pump automatically. You can also monitor the water level on the Blynk IoT app.

In Manual mode, you can control the water pump with a switch and Blynk app. The alarm will ring when the tank is full, and when the water level drop below the threshold limit the pump with automatically turn off.

During this video, I have explained the complete circuit and source code.

During the ESP32 project video, I covered the following topics:
01:22 Explained circuit diagram of this ESP32 Project.
05:04 PCB for the IoT-based Pump controller.
07:08 Source code for the ESP32 project.
08:14 Set up Blynk IoT Cloud for ESP32
09:33 Set up Blynk IoT App for water pump controller

Important points:
1. Set the float switch ON and OFF distance as per the water tank height.
2. Use the relay module as per the pump rating. Here I have used 30A 5V SPDT Relay (Active LOW).
3. If there is no water in the underground tank the pump will not start.
4. If the float switch wire is damaged, the alarm will ring, after correcting the connection you have to press the push button as shown.
5. If WiFi is available, you can monitor the water level and control the pump from anywhere in the world from Blynk.
6. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltages.

This IoT-based water level controller will help you to maintain the water level in the tank, also it is very useful to save energy and water resource.

If you face any issues please let me know in the comment section.
