A Design of Multi-temperature Monitoring System Based on GSM

摘要

The multi-temperature monitoring system that was designed in the paper constituted by the monitoring center and a number of the terminals. It can monitor simultaneously several terminals. Each terminal is more than 10 meters distance apart and some terminals interval is between the walls. The monitoring temperature data that is from each terminal temperature data to the control center is transmitted through GSM network. What's more, an alarm signal will appear to the control center when the temperature exceeds the value of alert temperature.
