In this lab, we will design a simple temperature measurement system which uses a difference amplifier to increase the overall sensitivity of the thermistor.
The change of resistance for the thermistor is 3Kohms.
With the 10Kohms resistors set up for the wheatstone bridge.
We are able to boot the sensitivity of the thermistor to beyond 0.2V/degree C.
This is how the circuit is setup.
The video shows the measurement system is very sensitive.
