Project HARITHA - an automated irrigation system for home gardens

The maintenance of even a small garden gets tedious at times in the urban scenario. A fully automated system which optimizes the use of energy and water resources is the need of the day. In this paper, we propose the design and implementation of a highly energy efficient, multimode control for an automated irrigation system. The system uses an in-situ soil moisture potential measurement and the programmed data to irrigate a desired area. The soil moisture content is monitored by a microcontroller-based data acquisition and distribution system. An integrated GSM module provides critical information to the user during system failure. The proposed microcontroller based system was programmed and tested for its performance.
