THERMISTOR BASICS – Wavelength Electronics

The sensor has a small amount of current running through it, called bias current, which is sent by the temperature controller. The controller can’t read resistance, so it must convert resistance changes to voltage changes by using a current source to apply a bias current across the thermistor to produce a control voltage.

How to Obtain the Temperature Value from a Thermistor ...

Aug 18, 2020· A typical thermistor circuit provides a voltage (V Sense) that is applied to an ADC input; the ADC then converts this voltage to an LSB (least significant bit) digital value that is proportional to the input voltage. A common ADC resolution is 12 bits for many lowcost MCUs, so the formulas in this article will use 12bit resolution.

Voltage mode linearization is easily accomplished be placing a normal resistor in series with the thermistor and biasing the resulting resistive voltage divider with a constantvoltage source. If the normal resistor has the same value as R 25C , then the region of nearly linear output voltage versus temperature will be symmetrical around +25°C.
