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 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, finally 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.
