Study of long-term stability parameters of thermal sensors DS18B20

Authors: Suchkova L. I., Husseyn S. M., Yakunin M. A., Yakunin A. G.

Annotation: According to the more than two years of monitoring the temperature with two located in close proximity to each other temperature sensors it was found that the spread of their testimony for all the tests did not exceed the three least significant digits. In this case, the systematic error in this period did not change. This makes it possible to use the sensor as a precision tool to identify long-term fluctuations of temperature of a control object with sampling intervals less than 30 s and the absolute error not exceeding 0.1 ºC instead of 0.5 ºC, given the manufacturer in datasheet.
