E Health Agriculture Monitoring System through WSN

The water level required by each soil type varies tremendously. The improper maintenance of water in agriculture leads to water scarcity. The farmers working in the farm lands are solely dependent on the rain, river and bore wells for irrigation of the land. Along with that scorching summers threatens our planet every year, our farmers are unable to cultivate our traditional crops at their suitable seasons.. Temperature dependence of crop depends on whether that crop belong to “wet harvesting crops� or “dry harvesting crops�. Wet harvesting crops are those crops which depends on temperature or season, also they can be grown throughout the year. Hence with change in temperature, their water requirement changes Soil water level can be manipulated and accordingly irrigation can be done which can save a huge water that applied in the field in surplus amount. This research focuses on the design of a prototype using WSN to provide complete automation for the irrigation process In this modern era of agriculture the farm lands have water-pumps, drip irrigation system, but also manual controlling by farmers is required to turn the pump on/off whenever needed. In the proposed work WSN is used together to provide complete automation to the irrigation process. Sensor module includes Soil moisture sensor, temperature sensor and rainfall sensor. Selection of fields and the soil is done using WSN. Once the data is fed to the system the system follows the same configuration to water the soil. Water level of soil is maintained by switching on/off of pumps. Instead of calculating water requirement by different soils, the value obtained by the researchers in their researches is directly taken as threshold value for this prototype. The main aim of this prototype is to continuously monitor soil water level and irrigate the fields in proper duration with the exact required amount of water. Water requirement of soil varies with the type of soil. WSN is used to automatically water the soil in the required quantity.
