In my previous post about reading thermistors with a Wemos D1 Mini, I observed resulting output seemed a bit high at lower temperatures, while readings were lower compared to other sensors at higher temperatures. (If you haven’t read that post yet, you may want to check that first in order to understand the starting point…

Getting accurate NTC thermistor readings with a Wemos D1 Mini
A thermistor is a very common type of thermometer. They are cheap and readily available in many forms. Thermistors are simple devices. A thermistor is basically nothing more than a resistor that changes its resistance with temperature. Very popular are 10K NTC thermistors. Negative Temperature Coefficient (NTC) means that resistance drops when temperature rises. 10K…
