Abstract
The population boom and the scarcity of freshwater resources in the last century, has made it mandatory for humans to adopt modern agricultural techniques so as to meet the food demands. Agriculture is one of the major occupations in India and it accounts for about 13.7% of the GDP. However, there has been no significant growth in this sector for the past decade. It is estimated that by 2050, India will face a severe water shortage. This project aims at developing an automated irrigation system such that the usage of existing water resources could be optimized. In the system, a number of soil moisture sensors and temperature sensors are placed in the root nodes of the crops. The readings of these sensors are transmitted through modules to a gateway. The gateway manages the information provided by the sensors, triggers the actuators and sends the data to the cloud. The information given by the sensors are then compared in the gateway node, to the predetermined optimum values of temperature and soil moisture so as to control the switching of the water pump. Because of the low cost and user friendly architecture, the system can be implemented and be useful for the farmers in geographical areas with water scarcity.
