ABSTRACT
As the era of progress and development, microcontroller technology has spread to our life, work, scientific research, each domain, has e a more mature technology, this paper mainly introduces a AT89S51 MCU based on temperature measuring system, described in detail by using digital temperature sensor DS18B20 development temperature measuring system, focus on the process of the sensors in the single-chip puter hardware connecting, software programming and each module system flow on the detailed analysis, part of the circuit also introduced one, the system is easy to realize the temperature gathering andLED display, and can according to need any set upper temperature, it USES up police is very convenient, with high precision, range wide, high sensitivity, small volume, low power consumption advantages, suitable for our daily life and work, agriculture of temperature measurement, also can be used as temperature processing modules in other systems, as embedded auxiliary extended to other main system. DS18B20 and realize the minimalist bining temperature detection recorder, the system structure is simple, strong anti-jamming capability, suitable for harsh environment temperature measurement on the site, have broad application prospect.
Keywords: AT89S51 Digital sensor DS18B20 Display LED;
