The Study Of Remote Temperature And Humidity Environment Parameters Wireless Monitoring System Based On GSM

With the development of industrial and agricultural production, the requirements of temperature and humidity environment have become higher and higher, which makes the measurements and controlling applications of the temperature and humidity become more widely. Many industries have proposed high demands to the environment of temperature and humidity: which needs precise control of temperature and humidity in many fields of storing food, breeding heating plant, making large scale integrated circuits, Pharmaceutical Biochemistry and so on. Therefore, the monitoring and controlling of the temperature and humidity have become the very important technical requirements in the productive process.In this paper, the remote temperature and humidity environmental parameters wireless monitoring system can be continuous, synchronous on the temperature and humidity data acquisition and processing. The system can detect and collect the environmental parameters of temperature and humidity which are around the detector. It also can monitor the environmental changes. The system mainly contains temperature and humidity probe, data acquisition and wireless transmission part and data management software part.I use the analog circuits and digital circuit design temperature and humidity probes. The circuits can make the parameters of resistance and capacitance converted into a linear output voltage signal. The system use the MSP430 scm as the microcontroller which is for A/D conversion and control of wireless modules, and also select the TC35i which is the GSM wireless module for data transmission. Data management software is designed by delphi7.0 software to realize synchronous data display, data curve analysis, historical inquiries etc. In this paper, the design of the remote temperature and humidity environmental parameters wireless monitoring system is reasonable and stable after the actual verification. Temperature and humidity measurement and data acquisition is accuracy. The system can transmit the data synchronously. Wireless transmission of data can overcome regional and limitations of the traditional forms. It provides remote monitoring of temperature and humidity environment a powerful mean.
