Jan 21, 2018 · The thermistor changes its resistance with temperature so we can measure that change using one of the Arduino’s analog pins. But to do that we need a fixed resistor (not changing) that we can use for that comparison (We are using a 10K resistor). This is called a voltage divider and divides the 5v between the thermistor and the resistor. It can be used to measure temperature, or to sense temperature changes and act accordingly for the temperature changes, depending on its designed use for the circuit. There are 2 main types of thermistors; negative temperature coefficient (NTC) thermistors and positive temperature coefficient (PTC) thermistors.

For this reason, you may see the thermistor referred to as a Negative Temperature Coefficient (NTC) device. As an example, suppose you purchased a thermistor that measures Ro = 10k at To = 25 and has a material constant Beta = 3548. The device should measure resistances across a -15 to 65 deg C range that look like Since the thermistor is a variable resistor, we'll need to measure the resistance before we can calculate the temperature. However, the Arduino can't measure resistance directly, it can only measure voltage. The Arduino will measure the voltage at a point between the thermistor and a known resistor. This is known as a voltage divider.For accurate temperature measurement, the probe of the bimetallic-coil thermometer must be inserted the full length of the sensing area (usually 2 to 3 inches).
