This project presents a Solar Powered Automatic Water Level Controller for overhead tanks in apartments. A microcontroller continuously monitors the water level using sensors and automatically switches the water pump ON when the water level is low and OFF when the tank is full, preventing water overflow and dry running. The system is powered by a solar panel, with excess energy stored in a battery for operation during nighttime or low sunlight conditions. This intelligent system conserves water, reduces electricity consumption, and provides an efficient, eco-friendly solution for automatic water management.        

The main objectives of the project are:  

1. Automated water pumping system.
2. Usage of solar energy.
3. Provision for switching pump during nights.

       

The major building blocks of this project are:

1. Regulated power supply.
2. Microcontroller.
3. Electromagnetic Relay.
4. Solar panel.
5. Water level sensor.
6. Crystal oscillator.
7. Reset.
8. Battery.
9. LED Indicators.

        Software’s used:    

1. PIC-C compiler for Embedded C programming.
2. PIC kit 2 programmer for dumping code into Micro controller.
3.  Express SCH for Circuit design.
