Title Temperature acquisition system design based on
Single-chip control
Abstract
The design of temperature acquisition system in industrial production in the use of more. The design of integrated chip, sensor technology, product design to collect four channel temperature. This paper is the use of AT89S52 microcontroller as the main control unit, the use of assembly language programming. Through the digital temperature sensor DS18B20 collecting temperature, and then use the8 bit LED to display the temperature, if the temperature is above a certain temperature, with a buzzer alarm circuit, will generate alarm to remind, finally, through the serial communication to collect on the temperature data is transmitted to PC. This paper is the design of hypogynous machine, is mainly responsible for the acquisition of four channel temperature, transmitted to the microcontroller, display module receives a signal, display real-time temperature.
