Welcome to the world of technology and innovation! In this article, we will explore a fascinating project that involves creating an automatic water pump controller circuit using the versatile 555 timer IC. This circuit allows you to connect your existing pump starter and control the pump in both auto and manual modes. The best part is that you can easily build this project with the help of a comprehensive circuit connection diagram shared in this article.

An Introduction to the Project
Imagine a scenario where you no longer have to worry about manually turning your water pump on and off. With the automatic water pump controller circuit, that dream becomes a reality. This project leverages the power of the 555 timer IC to create a system that monitors the water level in your tanks and controls the pump accordingly. Whether you have an overhead tank or an underground tank, this circuit has got you covered.
Understanding the Operation
To better comprehend how this project works, let’s break it down. The circuit consists of a 555 timer IC and a 30 ampere relay, which allows you to control a wide range of pumps. The relay is connected to the existing manual switch of the pump circuit, enabling manual control if needed.
To switch to auto mode, you simply turn off the manual switch and turn on the auto switch. From that point on, the 555 timer IC takes charge. It continuously monitors the water level in both the overhead tank and underground tank. If the water level falls below a certain threshold, the pump starts automatically. Conversely, if there is no water in the underground tank, the pump shuts off to prevent damage.
Additionally, the auto switch serves as an emergency stop. If you ever need to quickly turn off the pump, simply flip the switch, and power to the relay coil will be cut off, stopping the pump instantly.
Building the Circuit
Now that we understand the inner workings of the project, let’s dive into the construction process. We will utilize the LTM PCB designer software to create the circuit layout. The software not only simplifies the design process but also offers features like data management and collaboration with fellow team members.
Once the layout is ready, we can proceed to make the actual PCB using the Zero PCB. The video accompanying this article provides a detailed step-by-step guide, showcasing how to match the layout with the holes on the Zero PCB.
With the PCB in place, it’s time to gather the necessary components and connect them according to the circuit diagram. Always exercise caution when working with high voltage, ensuring the proper safety measures are in place. Following the connection diagram, attach the AC supply, water level sensing wires, and pump to the PCB. The relay should be connected across the existing manual switch of the pump starter. Lastly, remember to take advantage of the grid on the layout to make the connections easily.
Enjoy the Convenience of Automation
Once everything is connected and soldered, you’re ready to experience the wonders of automation. In manual mode, you can control the pump using the switch. Simply turn it on, and the pump starts. Conversely, turning it off stops the pump.
To switch to auto mode, turn off the manual switch and turn on the auto switch. With this action, the 555 timer IC takes control, ensuring the pump starts when the water level falls below the red wire and stops when the water level reaches that threshold.
If you don’t have an underground tank, simply short the two terminals mentioned in the circuit diagram. This modification allows the 555 timer IC to focus solely on monitoring the water level in the overhead tank.
Conclusion
In conclusion, the automatic water pump controller project opens up a world of convenience and efficiency in managing your water supply. With minimal effort and the right components, you can build this circuit and enjoy the benefits of automation. Say goodbye to frequently turning your pump on and off and embrace the power of the 555 timer IC in controlling your water pump seamlessly.
