这个是在keil上用C编写的一个程序，是我在学校做的一个创新工程项目，主要功能是实验，检测玻璃跟室内温度，然后通过单片机计算露点温度算出汽车挡风玻璃的起雾温度，进而通过继电器控制汽车空调的开和关。由于程序还不是最完美的，还存在一些不确定因素，例如继电器的控制有延时，露点公式的精确等，其他功能齐全。-This is a program in keil written in C, is an innovative project that I do in school, the main function is to experiment, to detect glass with room temperature, and then calculate the dew point temperature is calculated through the microcontroller car windshield fogging temperature, and then through the relay to control the air conditioning on and off of the car. The program is not perfect, there are still some uncertainties, such as relay control delay, dew point formula accurate, the other full-featured.
