Some measurement equipment in the wild or in the unattended condition, if the GSM Short Message module is installed in the transmission of data, can transfer system based on GSM public network, and the system reliability, anti-jamming, stability, maintainability, function etc advantages Obviously, and can reduce the operation cost and labor intensity. Temperature is one of the important parameters for measurement and control in the industrial production process, in the national defense, military, scientific experiments and industrial and agricultural production process, which plays an important role in measurement and control of temperature. The system described in detail the system design and the realization process of GSM module based on the multi channel temperature monitoring alarm. Implementation of remote wireless monitoring of the ambient temperature device through the GSM network, the realization of intelligent industrial equipment operation, modernization. System using STC89C52 microcontroller as the core of computer, communication mode using the GSM module of TC35i, intelligent temperature sensor DS18B20 produced by DALLAS company 1－Wire line as the temperature measuring device. Mainly realize the acquisition of the temperature monitoring, display the temperature value, set temperature alarm value, the buzzer alarm, real-time monitoring of temperature messages to users at the site. This system is based on C51 programming language as a tool, system program is written in code. In keil programming environment for the platform, through the overall system design, can be
