consists of a voltage reference, a log amp, an integrator, a comparator, and a USB data-acquisition module. The figure shows a simplified schematic. A log amplifier and integrator form a linearizing ...

For example, when you combine a thermistor’s radically nonlinear exponential resistance-versus-temperature-response curve with a linear signal conditioner (Reference 1), the resultant graph resembles ...

The first step is a thermistor, a conceptually simple device ... But by using the right analog reference voltage and adjusting the voltage divider he could get a 20x improvement in resolution, ...
