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,
