在传统的模拟信号远距离温度测量系统中,需要很好的解决引线误差补偿问题、多点测量切换误差问题和放大电路零点漂移误差问题等技术问题,才能够达到较高的测量精度。而新型数字温度传感器 DS18B20的出现,为克服上面提到的三个问题提供了很好的解决方法。Dallas 半导体公司的数字化温度传感器 DS1820是世界上第一片支持“一线总线”接口的温度传感器,在其内部使用了在
In the traditional remote temperature measurement system for analog signals, it is necessary to solve the technical problems of lead error compensation, multi-point measurement switching error and zero-point drift error of the amplifier circuit, so as to achieve higher measurement accuracy. The advent of the DS18B20, a new digital temperature sensor, provides a good solution to overcome the three problems mentioned above. The Dallas Semiconductor Digital Temperature Sensor DS1820 is the world’s first temperature sensor to support the “one-wire bus” interface and is used internally by
