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, athermistor module picked my interest, mostly because I had never used one before.
The thermistor module I got came as a thermistor and an op-amp on a PCB. I hooked it up to an Arduino’s analog input pin and sure enough I could see the input data change when I exposed the sensor to warm air.
A really good summary of how to use thermistors and solve the Steinhart-Hart equation.Related
