    These low-cost ICs are very easy to use.
    BRUCE -- honolulu, HI   1/16/2010
    Simple and cheap solution. A .1mfd ceramic cap across the output and ground will provide a more stable reading when using remotely.
    MICHAEL -- rose hill, KS   5/17/2009
    Parts were not shipped with order but were replaced immediately.
    GEORGE -- glyka nera, XX   11/2/2006
    Already tested, about to be installed, works fine as well. A circuit diagram would be nice on the packaging. The user currently needs to either log on to and look at it or search for the component data sheet on the net.

    Great product! I like these IC's. I use them with ELK, Stargate, Comstarr automation controllers. Works great as standalone temperature sensor. For best results, build an (OP AMP) operational amplifier circuit to change resolution to 1 degree increments. (3 wire connection)
    MICHAEL -- dearborn hts, MI   12/12/2004
    This is an excellent value.
    ROBERT -- boonton, NJ   10/19/2003
    I built them into temp sensors - works
    ANDREW -- bellevue, WA   8/18/2003
    Got it working but would have prefered more tech information and examples of its use
