Abstract:This paper introduces a single-chip microcomputer AT89C51 as the core of the air conditioning temperature control system. Design principle of the air conditioning temperature control system in order to achieve a better system for the purpose, By the temperature sensor DS18B20 to complete the collection of temperature, The data is processed by the single chip microcomputer,Through the LED display.With in the normal environment for the system to measure the temperature in order to determine the conditions, the use of single-chip microcomputer control system of air conditioning refrigeration and heating to achieve the required temperature, Through the electromagnetic relay to control the operation of the compressor. Project is in a normal environment temperature measurement, the system design and the selection of the device is carried out on this basis.
