这是用热敏电阻传感器输出的电压模拟量经模数转换器转为数字量,再由单片机处理后由四位一体共阳数码管显示的数字温度计(高温可报警)-This is the voltage simulation quantity which outputs with the thermistor sensor transfers the digital quantity after the modulus switch, again after monolithic integrated circuit processing demonstrates the digital thermometer by the quaternity altogether positive nixietube (high temperature to be possible warning)
