三、模数转换器应用举例现在利用前面所介绍过的内容,作一个用μP程控的测量装置的实例。设欲测某一现场(如温室或仓库)中的温度。此被测温度可以先用温度传感器转换为在所采用的ADC要求的输入电压范围之内,如按转换准确度的要求,采用10位DAC,则此传感器与μP之电路完全可以采用图4—7之电路。如果需要将已存入μP之数据在电平记录仪上画出以时间为函 Third, the ADC application example Now using the content described above, as an example of μP programmable control device. Set the temperature in a site (such as a greenhouse or warehouse). The measured temperature can be converted to a temperature sensor using the required ADC input voltage range, such as the conversion accuracy required by the use of 10-bit DAC, then the sensor and μP circuit can be used in Figure 4- 7 of the circuit. If you need to store the data that has been stored in μP on the level logger in time,
