说明：  由温度传感器将采集到的温度信号转换为电信号后，经过放大器放大成DSP能接收到的电压信号，并对此信号进行滤波、整形，然后送入DSP内自带的A/D转换器的模拟输入口。
(Will be collected by the temperature sensor the temperature signal is converted to electrical signals, the DSP through the amplifier into a voltage signal can be received, and this signal filtering, shaping, and then comes into the DSP within the A/D converter analog inputs.)
