DS18S20温度传感器的高精度测温及校正算法
Algorithm of high-precision temperature measurement and calibration for temperature sensor DS18S20
摘要
Abstract
An algorithm on temperature measurement calibration for the digital temperature sensor DS18S20 is proposed in Reference [1],but it can′t make full use of the data given by DS18S20 registers to represent the temperature value from the sen⁃sor exactly. In addition,the algorithm does not pay attention to the calibration of temperature measurement. A accurate algorithm for temperature measurement is presented in this paper,which can derive the temperature values from the DS18S20 sensor. The calibration of temperature output value of DS18S20 is investigated in this paper. The calibration expression based on the least square method is offered. By dint of the measuring instrument with high precision,the calibration expression was developed. The simuliation results indicate that the calibration expression can greatly improve the measurement precision,and its measurement error is less than 0.01℃.关键词
