基于AT89C51和DS18B20的最简温度测量系统 温度检测的传统方法是使用诸如热电偶、热电阻、半导体PN结之 类的模拟温度传感器。信号经取样、放大后通过模数转换，再交自单片机处理。被测温度信号从温敏元件到单片机，-Based on AT89C51 and Jane DS18B20 most temperature measurement system temperature detection is the use of traditional methods such as thermocouples, thermal resistors, semiconductor PN junction, such as analog temperature sensor. Signal sampling, amplified through the analog-digital conversion, and then deal with pay since the single-chip microcomputer. The measured temperature signal from the thermo-sensitive components to the microcontroller,
