DESCRIPTION

  DS18B20
The DS18B20 (3) is one of several available 1-wire temperature sensors. It is the replacement for the DS18S20 (3) Alternatives are DS1822 (3) as well as temperature/vlotage measurements in the DS2436 (3) and DS2438 (3). For truly versatile temperature measurements, see the protean DS1921 (3) Thermachron (3).
The DS18B20 (3) can select between 4 resolutions. In general, high resolution is the best choice unless your application is truly time-constrained.
