# A kind of long distance wireless farmland monitoring system and method Patent Number: CN105830870B This patent details a long range farm monitoring system. In particular, it describes how to acquire sensor measurements on crop growth. This data is then processed by a cloud computing solution, which sends commands to an irrigation control system that can dynamically adjust the watering of the crops to maximise growth. This in turn reduces the manual labour needed for irrigation, increase crop yield and saves water. This patent is less applicable as they are using ZigBee communications. However, they do specify how nitrogen and phosphorus levels are to be monitored which may conflict with our NPK data sensing. ## References 1.
