lduncan Posted February 14, 2006 Report Share Posted February 14, 2006 Dallas 1-wire Temp Sensor. Is it running through a PC serial port? Layton Quote Link to comment Share on other sites More sharing options...
Rocketman Posted February 14, 2006 Author Report Share Posted February 14, 2006 http://www.maxim-ic.com/quick_view2.cfm/qv_pk/4379 no it's a little stainless steel module ( about the size of a ten cent piece ) setup required via PC , but then you just place the device whereever you want to measure.

Rocketman Posted February 14, 2006 Author Report Share Posted February 14, 2006 costing is dependant on which model you chose . for the basic model including the serial port adapter and reader & Fob about US $60 plus shipping ( very expensive for single items ) Quote Link to comment Share on other sites More sharing options...
lduncan Posted February 14, 2006 Report Share Posted February 14, 2006 are these things expensive? Dallas / Maxium's free sample service is pretty efficient. You can get the iButton through that (worth US$25 in itself), but you still need the serial port adaptor and accessories. Layton Quote Link to comment Share on other sites More sharing options...
