GPRS-based environment monitoring system and its application in apple production

This paper mainly presented a research in which a GPRS-based environment monitoring system (GEMS) was developed to collect meteorological data influencing apple production. The data collected are transmitted to a web server through GPRS service, and meanwhile replicated and stored in a SD card for avoiding the loss. The system has been deployed into 5 different main apple production regions in Yunnan province. Via two-year test, the research showed that GEMS is functional as regards to monitoring the environmental factors which influence apple production, which hence provide real-time service for registered farmers to guide their work.
