In order to implement accurate measurement of multi point temperature, an intelligent granary temperature monitoring system based on single chip microcomputer （SCM） is designed in this paper. The system uses SCM as main control chip and adopts tempera- ture sensors, 12864 liquid crystal display （LCD） monitors, keys, alarm devices and CH340 communication modules. The alarm temperature, real time temperature and its change curve of each measurement point can be displayed. The system can also adjust the alarm temperature and communicate between SCM and host computer. Test results show that the temperature monitoring system designed in this paper has the advantages of convenient debugging, high accuracy and good reliability. Therefore, it greatly facilitates the implementation of temperature real time monitoring.
