And for those people who are producing cash crops, i can propose a better way of Intelligent farming which we are doing in Yuktix at present. We are doing 2 way communication through GPRS module + MCU (Micro-controller unit) + sensors (Humidity + Temp + soil wetness + soil temperature) + Leaf Wetness sensor for some greenhouse and cash crop farmers. Let me know if this thing seems to be of any interest.
I can help out in figuring the best possible hardware + software solution if we want to do in DIY manner for non-cash crop farmers.
