Abstract
In the industrial and agricultural production and daily life, the right temperature measurement and control occupy a very important position. In the fire temperature detection non-destructive electrical, power, munication equipment failures to predict overheating detection, air-conditioning system, temperature measurement, all kinds of means of transport of ponents overheating detection, security and surveillance system applications, the temperature of medical and health consultation testing, chemical, and mechanical equipment such as temperature overheat ... detection, temperature detection systems have a wide range of applications.
This design of multi-channel temperature measurement system is through proteus simulation, using microcontroller AT89C51 puter as the controller, using digital sensor DS18B20 for temperature measurement, the temperature of multi-location real-time detection and through LED display device displays the temperature function can be easily used in various temperature detection occasions. This design uses DS18B20 and AT89C51 microcontroller developed a temperature circuit detection system.
