STUDY ON THE FIELD SOIL MOISTURE MONITORING SYSTEM BASED ON GSM-SMS TECHNOLOGY

摘要

Modern precision agriculture depends on the acquisition of real and accurate field data. A study on GSM- SMS technology application to field soil moisture acquisition was presented in this paper. This study is based on a field data collection system which composed of PC, field monitoring sensors, TC35i modules and ATmeg32 microcontroller. The data transmissions and communication are all accomplished by adoption of GSM -SMS technology. After establishing the monitoring system, the authentication and performance tests were conducted in Xiaotangshan Beijing. Based on results of the performance test over 1 year, we can see that the integrity and performance of transmission is guaranteed. The GSM-SMS technology is well suited for implementation in field data monitoring and acquisition. GSM - SMS technology application to field data acquisition system is cheap and feasible.
