Physics electrical sensor system questions?

In this question, you are to discuss an electrical sensor system of your own choice.

1. State the physical variable of your chosen sensor system and a suitable component to make the sensor.

I choose voltage and a voltmeter.

2. Draw a circuit diagram and how an electrical output signal can be obtained from the circuit?


3. State how you could calibrate your sensor system and determine its sensitivity?


4. Give an estimate of the sensitivity?


5. Suppose that your electrical system is not sufficiently sensitive, state and explain how you would modify your circuit to improve the sensitivity, other than by using a more sensitive sensor?
