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.\n\nOne-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.\n\n**Please note:** This is the parasitic power version of the DS18S20. Pin 3 is a No Connect (NC) pin.\n\n**Documents:**\n\n* [](http:\/\/datasheets.maxim-ic.com\/en\/ds\/DS18S20-PAR.pdf)\n\n* [Datasheet](http:\/\/datasheets.maxim-ic.com\/en\/ds\/DS18S20-PAR.pdf)\n\n","date_published":"2010-04-06 14:08:01-06","price":4.25,"qty_price":{"1":4.25},"in_stock":false,"backorder_allowed":false,"is_rohs_compliant":true,"is_export_controlled":false,"is_oshw":false,"in_eagle_library":false,"in_fritzing_library":false,"sparkfun_original":false,"hstariff":"","pack_length":"mm","pack_width":"mm","pack_height":"mm","packed_weight":"0.0100lbs","ascii_art":" .. .. ... .. . ... ...... . . . .. . . . . .. .\n . ... ... .. .. .. .. . .. .. . .. . .. .\n .. . . . . . ... .. .. .. .. .. . . .. .. ... .. ..\n .. .... . .. .... ... . . . .. . .. . .. . ... .\n .. . . . .. ..loc,.. . .. .. ... . ..\n . . .. . . . . .dXXXXX0xl:'... .. .. .. ..\n . .. .. ... . .. .. . . . ..kXXXXXXXXNXXKko;'. . .. ... .\n . . . .. . .. . .kXXXXXXXXXXXXXXXXX0xl;. .... ...\n . .. .. .. . .. . .OXXXKXXXXXXXKXXXXXXXXXXx. . . ..\n . .. ... .. . . .kXXXXXXXXXKXXXXXXXKXXXXxl. . ..\n . . .. .. . .
