Temperature sensor – A trip to Steinhart-Hart, Gaussian elimination and thermistors

I made a thermistor-based, water-resistant temperature sensor to be used with a micro controller. Here I document the process on how to get the thermistor calibration data.

Recently, my friend w0z visited after 28c3 and we ended up checking out Segor, a brick-and-mortar electronics shop in Berlin. It's to me like a candy shop is to kids. Among other things, a thermistor module piqued my interest, mostly because I had never used one before.
