Introduction: Water Pump Automation

By

In this Project, I show you how to make water pump automation system by using ultra sonic sensor. This system is fully automatic, no need to switch ON or OFF water pump. When water level down in water tank, this system automatically switch ON the pump and then water level reaches upper level of the tank, this system automatically switch OFF pump.

Supplies

For making this, i am using:-

1. Arduino Uno https://amzn.to/3nFSniX

2. Transistor BD139 https://amzn.to/3GsBYqS

3. Ultrasonic Sensor HC-SR04 https://amzn.to/3GsBYqS 4. 12volt Relay https://amzn.to/3GsBYqS 5. LEDs https://amzn.to/3GsBYqS

Step 1: Connect Arduino to Computer and Open Arduino ID Software

Step 2: Upload Code to Arduino
