Abstract: Text design is a series of refit design based on the traditional air conditioning
temperature controller. After consulting the relevant information, I designed a temperature
measurement and control system based on STC89C51 single chip microcomputer. The circuit
uses DS18B20 as the temperature monitoring element, uses LED digital tube as the module
display, and uses the keyboard to set the temperature range of refrigeration and heating. When
the temperature exceeds the set range, there will be led and buzzer sound and light alarm
prompt, at the same time, there are refrigeration and heating devices to work, making the
temperature constant in a range. The software of the system is compiled with 8051C language.
After simulation, it is proved that the whole circuit is correct and achieves the expected effect.
The system has the advantages of low power consumption and high sensitivity. It can quickly
detect the change of temperature, process and judge the results, and respond immediately. It
has good practicability.
