Abstract
Temperature monitoring and control is a very important part of the production
process, since ancient times by people concerned with people's lives. In recent years,
with the development of society, people on the accuracy of temperature monitoring
and scope have higher level requirements, both in industrial and agricultural
production, or scientific research, are particularly important for temperature
monitoring. So the temperature monitoring study design is necessary.
This topic introduces the STC89C52 microcontroller core, DS18B20 sensor set
as the collection, processing, display, automatic control as one of the storage
temperature monitoring system. Throughout the system, the PC as a PC monitor
module, STC89C52 microcontroller as the next-bit machine control module, the PC
and the next crew to serial data transmission and exchange of communication manner.
In this paper, intelligent sensor DS18B20 temperature acquisition and conversion,
which has a wide temperature range, high precision, but also has a single bus interface,
which makes circuit design more concise. STC89C52 microcontroller with a
computing speed, processing power and other characteristics, so that in the
temperature measurement and control systems to become a very important part, along
with the development of electronic technology, the use of single-chip temperature
measurement and control, will become a trend. The system is also set temperature
display module and alarm device, can artificially control the temperature, the lower, it
can automatically adjust the temperature, so that users can better control the
temperature.
Keywords: microcontroller, DS18B20, temperature monitoring.
