This is a model of what we plan our product to be like. The soil moisture sensors wirelessly comunicate with eachother and communicate back to the base arduino at the farmers home, which communicates with the farmer's phone. The arudinos will be placed aprox. 101m apart so that the soil moisture sensors can still get an accurate reading and still communicate with eachother. The arduino in the waterproof box is just incase their is failure with communication so that once it gets in range it can automatically begin watering the crops. The tank levels are measured by a level sensor.
