Design of Temperature Acquisition System Based on STC89C52RC Single-Chip Microcomputer

摘要

The temperature is an important physical quantity that is closely related to daily production and life. We need extract temperature information on many occasions. Temperature acquisition system based on signal chip machine, temperature sensor, serial communication and VB knowledge is designed in the paper. The system can read temperature data from the sensor, and then display it on the liquid crystal screen. At the same time temperature value is transmitted to the PC through the serial communication, PC can display the real-time temperature value. The test results show that the system has advantages of rapid response, and can better display the actual environment temperature, moreover, the system circuit design is simple with lower cost and smaller size, and can be applied in many fields of temperature detection.
