Thermistor Driver Board
This board was made in support of the below video for getting temperature measurements using some bead thermistors.
This project is for a board for getting thermistor readings into a 5VDC ADC like on an Arduino or the like. It is intended for using two thermistors per channel, with one thermistor on each leg of a wheatstone bridge to increase the sensitivity. The below sketch shows the general idea.
The balancing thermistors were sized (27.4k) to produce 0V output at 0 degrees C, and just under 5V output at 100 deg C, as shown in the below plot.
