Abstract

An automated irrigation system was developed to optimize water use for agricultural crops. The system has a distributed wireless network of various parameters like soil-moisture, temperature sensors, humidity sensor, light etc. The total system architecture includes a set of sensor nodes, a base station, and an internet data centre. With an ATmegh32 microprocessor and embedded operating system, screen display, system configuration and GPRS based remote data forwarding. Through a Client/Server mode the management software for remote data centre achieves realtime data distribution and time-series analysis. Farmers go through large financial losses because of wrong prediction of weather and incorrect irrigation methods. In this paper, with the evolution of sensor devices coupled with wireless technologies, it is possible remotely monitor parameters such as moisture, temperature and humidity.
