Intelligent Temperature Detecting System

Intelligent temperature detecting system has been widely used in military and civil fields. A novel intelligent temperature detecting system based on AT89S52 and DS18B20 is designed and implemented in this paper. The system uses AT89S52 to control the whole temperature detecting system, the detected temperature can be not only displayed in LCM1602 liquid crystal module, but also sent to PC by RS-232 serial interface, displaying in the way of digital and wave. In addition, when the temperature value exceeds the set ultimate value, the system will auto give an alarm. For the system has many merits such as strong anti-jamming ability, small volume, and low power consumption, it has important value for many practical applications.
