Automobile air-conditioner control system based on STC12C5A60S2 single-chip microcontroller

摘要

Recent years, automobile air-conditioner control system is particularly important as the automobile air-conditioner is becoming an important indicator to measure the comfort of a car. This paper introduces the hardware and software design of the system based on STC12C5A60S2 microcontroller. The hardware design part includes the circuits design of motor and fan, and the software design part describes the way to realize the modes conversion function. Experiments show that the automobile air-conditioner system can reach high control accuracy and it's practical.
