Smart orchard soil moisture monitoring system based on wireless communication technology

This system cored with a low power consumption mode of the MSP430F149 is equipped with a water content reflectometers, a automatic solar power supply module, GSM wireless asynchronous module, flow sensor module, Solenoid valves etc. to realize the functions of the orchard soil data's remote transmission and automatic precise irrigation. When achieved the lower limit of soil moisture^[1] in the collection process, the Collection terminal uses the long-range wireless communications technology to send the humidity data collected by SMS to the user's phone to warm through the GSM module. On the actual situation, the users can reply by phone, and then the controller detects users' command, Anally uses fuzzy control technology for precise irrigation. Through the practical operation, it shows that the system is reliable and stable and remotes Human-Computer Interaction and precise irrigation. Also it meets the actual needs of a wide range of the orchard area's cabling inconvenience. Compared to manual irrigation methods, it saves 20% to 30% of the water and tests results significantly.
