Today I walk through how to interface a standard automotive coolant sensor with an Arduino. They are a simple thermistor in an industrial style casing and output a resistance with changing temperature. In order to read it with an arduino you must use a voltage divider and then use the steinhart equation after calculating the resistance to find temperatures at varying resistances along the sensors value curve.
Code and excel sheet linked below. If you have any questions please comment below or e-mail me below.
Stay tuned for more videos!
