This document describes a precision agriculture system called KrishiSENSE that uses wireless sensor networks and a knowledge base to help farmers manage variability in their fields and crops. It collects data from sensors monitoring soil temperature, humidity, solar radiation, and other factors. This data is fed into a knowledge base along with crop and location information to provide farmers with customized suggestions on irrigation schedules, pest control, fertilizer use, and more. The system was created by students using an EZ430RF2500 wireless sensor network kit and could be implemented as a desktop app, wireless sensors, or using GPRS/GSM modules for cellular connectivity.
