Soil Moisture Monitoring and Control System Based on CC1100

In order to save water,reduce the costs of labor and production,and monitor the soil moisture real-time,a kind of soil moisture monitoring and control system was designed based on CC1100.Each node used a 9 V battery,no other external power source,which was suitable for a variety of environments.Meanwhile,in order to increase the scope of the system,there were two control modes,namely,timing control mode and soil moisture sensor control mode.Timing control mode enabled that we could set the time of drip irrigation and how long the drip lasts.This mode was simple and cost low and can extend the life of battery;sensor control mode not only enabled drip irrigation on-demand based on soil moisture conditions,provides a reasonable humidity,but also could improve the water resource utilization.At the same time soil moisture data and node status would be sent to the upper machine through the CC1100.
