Please help me to choose cable to extend TO-92 sensor legs

HKPhysicist
HKPhysicist 9 months ago

Hello E/E Engineers,

I am in the way of choosing cables to extend this TO-92 type temperature sensor legs so that I can place it under the target battery or even extend it into a refrigerator / freezer.

MCP-9700A

I know there is out-of-box 1-wire sensor packaged with long cable lead but the part`s origin is in question.  I must create this by myself so that I have the part`s origin documents.

    That isn't a problem. You can calculate exponentials on pretty much any modern micro but its a little slow. If you want to conserve power or time then precalculate third order polynomial coefficients from…

    Since the drain wire is connected to the shielding, it's more of a ground than a shield, but since the other wires are twisted pair it should work..

    HKPhysicist You can always go with one of the Maker's best friend - hot glue. That's what I used way back in 2021 during Build Inside The Box . I'm not sure how much it will shrink in the cold, but at…

    Why not use a thermistor.

    Much cheaper only 2 wires needed - use low cost single screened audio cable.

    Put a big capacitor across it (you don't need a fast response) .

    You suggested part requires exponential calculation to get the temperature, while other vendors provide built-in compensation so that programmers can use a linear equation to get the temperature.

    there are existing efficient algorithms and libraries to look up temperature for thermistors. Also for embedded use.

    That isn't a problem. You can calculate exponentials on pretty much any modern micro but its a little slow. If you want to conserve power or time then precalculate third order polynomial coefficients from the thermistor data and this will be quite accurate and very fast. You only need to do it once and your micro has to do three multiples and three additions.

    Taylor Series expansion can help in this case!  Grin

    But I still want a larger thermistor for the sake of easy assembly.
