E- Krishi: An IoT based Smart Irrigation System
Food production for 9.6 billion people by 2050 is a challenge with limited arable lands, increasing fresh water supply and climate change. There is a need to provide a smart solution to maximize yield from the agriculture fields with limited resources. E-Krishi is a smart irrigation system using automation, Internet-of-Things (IoT) and cloud computing. The proposed system provides smart irrigation schedule to crops to ensure adequate amount of water in fields for healthy growth of crops and reducing wastage of water. It takes as inputs real time data, i.e. moisture content of soil and rainfall prediction in a particular field. It aids farmers in decision-making such as time and duration of water distribution in fields based on threshold values set by them. Moisture sensor is used to read the moisture content in the soil. If the moisture content is below particular level, the water pump automatically gets on. The watering of the crops can be delayed if there is a rainfall prediction.
