选择合适的数字式温湿度传感器，通过单片机读取现场温湿度，实时控制直流电机转速。即当温湿度分别于设定值比较，根据比较结果来控制电机转速。-Select the appropriate digital temperature and humidity sensors, temperature and humidity through the microcontroller reads the on-site, real-time control of DC motor speed. That is, when temperature and humidity settings, respectively, compared to the results based on comparison to control motor speed.
