Design of the Temperature acquisition instrument Based on Proteus

ABSTRACT:Temperature is one of the basic environmental parameters. It is of great significance to temperature measurement in all aspects of production and life. For example, refining links in the chemical industry, sintering of iron and steel industry, iron smelting links, food production and processing links in the food industry. Therefore, it is of great significance to study the methods of temperature measurement and control.

The design is realized by SCM temperature measurement and control system, through the LCD display the measured temperature. The system uses a temperature sensor DS18b20 chip, processing and display through the micro-controller, real-time display of the measured value. The article introduced the ATMEL company's AT89C51 series single-chip temperature measurement and control system and real-time display system design based on the hardware structure and its principle, design points and corresponding software are analyzed, including the realization of the software design process and program. The system structure is simple and practical, and the measurement accuracy and efficiency are improved.
