Many types of sensors have a nonlinear response. This limits both the range and accuracy of measurement. Analogue circuits can be used to compensate for the nonlinearity of the sensor. These circuits can be complex and inadequate to cope in many situations. There are a number of software techniques that can be used to compensate, more effectively, for the nonlinearities of sensors. These can rely on developing an accurate model for the sensor.

In this task you are required to explore different software based techniques to compensate for the nonlinearities of a negative temperature coefficient (NTC) resistor sensor and select one appropriate technique and justify your choice. A good literature review is required. Demonstrate your solution using LabView and/or Matlab by fully building a hardware prototype which incorporates an NTC temperature sensor. You are required to evaluate, in detail, the improved accuracy of the sensor.

You need to submit a written report detailing the following:

1. Introduction
2. Literature Review
3. Design and construction details
4. Testing
5. Results and analysis
6. Conclusions
7. References

NOTE
The value of the thermistor used is 150kohms and resistor 68kohms. the introduction and conclusion should be very good.
