Embedded System based Agricultural Field Monitoring System

摘要

Agriculture provides as one of the economic solid foundation to the majority of the rural India. Majority of the people in rural places establish their own farms for their livelihood. The conventional methods that they use require a lot of human labour and consume energy. There is no ideal irrigation method for all weather conditions, soil structures and variety of crop cultures. Because of lack of knowledge in the advancement of technology, many a times they suffer a great loss due to sudden change in weather conditions, lack of supply of water or excess supply of water as well as the use of fertilizers and insufficient capital to buy equipment's. This work proposes an embedded system based agricultural field monitoring design that develop and implement the use of different sensors embedded to an AVR microcontroller. The sensors incorporated are temperature, soil moisture and rain detector sensors. Based on the condition of the soil sensed by the soil moisture sensor and the condition of rain, it turns ON/OFF the pump for supply of water to the field. LCD is used to display the condition of field provided by the various sensors. This system is expected to allow the farmers in evaluating the soil conditions through which it can reduce the unwanted usage of water and allowing proper yield of crops as well as reducing human labour.
