Solar Based Smart Water Pump Control with Turbidity and pH Measuring System

The drinking water crisis is one of the prime issues in all over the world. Almost half of the populations of the world isolated from this blessing. Insufficiency of electricity plays a great role in their situations, as without electricity we cannot run a pump. Renewable energy is one of the suitable answers to solve the problem. The most effective resources of renewable energy are solar energy, which could solve this crisis. This research presents a performance analysis of the solar-based water pump controlling system and water quality measuring system using arduino mega. The main objective of this research is to automatically control the water pump and single-axis tracking for solar. Besides, the pH and turbidity of the reserve tank water show into the liquid crystal display (LCD) by using arduino's command. If the turbidity sensor senses the water is polluted then the automatically send the tank's water to the filter for purifying and if the pH level of the water is high or low, the device automatically stops sending the water to the supply. In both cases turbidity low, pH high, and low), the GSM module sends a warning notification to the selected cellular device by using the arduino's command. This work is divided into two parts hardware and software systems. In the hardware part, four light dependent resistors (LDR) are used to sense the maximum light side from the sun. One linear actuator used to move the solar panel to the maximum light source location perceived by the LDRs. In the software part, the code is written by using C programming language and has targeted to the arduino mega controller. In this idea, arduino mega controls the whole thing. An automatic water pump can reduce the loss of pure water.
