The value of the resistor should be roughly equal to the resistance of your thermistor. In this case, the resistance of my thermistor is 100K Ohms, so my resistor is also 100K Ohms. The manufacturer of the thermistor might tell you it’s resistance, but if not, you can usea multimeterto...
The B value, also known as the “beta value” or “B coefficient”, of the thermistor gives you insight into how the resistance changes with temperature. You’ll need this value in order to calculate the temperature of the thermistor. Step 2: Connect the Arduino ThermistorCircuit To connect ...
