Replacement:SEN-00245. This product was retired because it requires parasitic power instead of the normal VCC/GND configuration, which is not as easy to use. This page is maintained for historical purposes only.

One-Wire Digital temperature sensor. Reports degrees C with 9 bit precision. Each sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus. This is a wonderful part that is the corner stone of many data-logging and temperature control projects.

Please note: This is the parasitic power version of the DS18S20. Pin 3 is a No Connect (NC) pin.
