Pollution of water is one of the main threats in recent times as drinking water is getting contaminated and polluted. The polluted water can cause various diseases to humans and animals, which in turn affects the life cycle of the ecosystem.

In our daily life water is essential not only for humans but also for agriculture so the quality of water is essential. In order to measure that, several sensors are used such as ph sensors, tubitity sensors and temperature sensors are used for agricultural fields. By using those sensors we analyze the water quality by using the standard values . By using those values we identify whether the water can be used for agricultural fields and this is very helpful for the farmers to increase their yields and the production is high so that we can decrease the poverty in the world. In recent years, intelligent sensor techniques have achieved significant attention in agriculture. It is applied in agriculture to plan the several activities and missions properly by utilizing limited resources with minor human interference.This system help to detecting water quality and use for agriculture purpose such as per reading of turbidity, ph level, electrical conductivity, temperature, acidity, alkalinity, total dissolved solids.We suggest suitable farming to farmers and also which diseases occur due to impure water.
