SOIL pH CONTROLLED IRRIGATION SYSTEM
In this processed system we are discussed about the ph control system using arduino. In this project we are used arduino board, LCD display, PH sensor, soil moisture sensor, power supply, relays and 3pumps. Also we are using ESP8266 module and it is required 3.3v supply. In this project we are taken 3 containers. So when ph is less than 7 then the solution is acidic. When the solution is normal then it is equal to 7 so it is ready for irrigation. And when the ph of solution is more than 7 then it is called alkaline solution.
