Abstract
This paper proposes an automatic system that treats the household waste water to obtain optimum pH which is suitable for crop irrigation. Each plant species has a preferred pH and in general, the optimal range for maximum plant growth is 5.4 to 6.8. For a healthy plant growth the quality of soil and water plays a vital role and the combined pH of soil and the waste water must be in the range of 5.5 to 7. Soil pH of the particular area is first measured and the pH of the waste water is treated in such a way that the combined pH will be suitable for plant growth. A hardware setup is presented in this paper to automate this process with the help of microcontroller, solenoid valve, DC motor and pH sensor. It also can be semi-automated with the help of microcontroller, solenoid valve, DC motor, 4×4 keypad and pH paper.
