As the current long-distance transmission of temperature and humidity data with wire has some deficiencies like hard wiring and high expenditure , a new remote wireless monitoring system of Tempera- ture and humidity data based on GSM is devised to avoid those deficiencies. The system include the design of acquisition terminal system of temperature and humidity data and the practice of terminal communica- tion software. Experimental results manifest the resonable structure of overall program, the character of flexible expansion, and practical design of hardware and software which can completel...
