MCKV Institute of Engineering introduces Smart Irrigation System to decrease the wastage of water in agricultural fields in India.
Farming is a major occupation for many people in countries like India, and it is the lifeline for entire population of the world. Water is the backbone of the farming industry. About 70% of the available freshwater is used in agriculture. As per India is censured, a huge amount of water is wasted in agricultural fields due to many reasons.

Over the years, different means of irrigation has evolved to minimise this wastage of water in agricultural lands. However, one of the major problem that still remains, leading to wastage of water, is the lack of proper knowledge of the farmers about the soil moisture content, and hence the requirement of the amount of water in the agricultural soil. More often than not, the carelessness of the farmers results in wastage of water. So considering the concern of water wastage, stress needs to be given for a better and smarter way of irrigation.
To deal with these problems, students of MCKV Institute of Engineering, Howrah have come up with the idea of a Smart Irrigation System that not only minimises the wastage of water in agricultural fields but also reduces farmer’s intervention in irrigation. In this project, resistive soil moisture sensors are placed deep inside the soil at different parts of the agricultural fields that checks the moisture content of the soil instantaneously. These sensors returns a value based on the soil moisture content to an Arduino device, which in turn operates the pump. These values differ depending on the moisture content of the soil. The Arduino device is the heart of the system. It checks the values of the sensors. Whenever the soil gets dry enough the Arduino device switches on the pump, thereby causing water to flow in the fields. When the soil gets adequate amount of water, the system switches off the pump. The values provided by the sensors at which the pump will be switched on and off will differ according to the types of soils and the kind of crops that are being harvested. These values will be set at the time of installation and a proper training would be required for the farmers to change these values in the future.

The aim of the project must not be restricted with developing it but also to provide a reliable and robust system at a feasible cost. So, cost of system and its maintenance cost are also need to be considered. Installation Charge for the proposed system in a land with area around 107ft² is estimated to be INR 17000 to INR 20000 which includes INR 8000 to INR 9000 (8 moisture sensor and Arduino system together with a central control) for circuit component of the system and rest as pipeline and pumping system cost and with a very nominal maintenance cost that may vary from INR 1000 to INR 10000 on yearly basis.
