To realize the real-time monitoring of city air quality, a remote monitoring system has been designed based on GPRS communications. The terminal node of this system using electrochemical sensors and MSP430F149 microprocessor to realize detection of gas saturation and data processing. Then the processed data was sent to a server central by adopting GPRS wireless module and stored in a database and complete the query,statistics and mapping and other operations by a specially designed software. This system that constituted with independent modules can be used flexibly.
