Sensor Project Preliminary Work My aim is to test how the sensor I have chosen reacts to an external change and compare the properties of three different sensors. The sensors I have chosen to investigate are thermistors named sensor A, sensor B and sensor C. To compare the 3 sensors I shall be primarily looking at their sensitivity and what purpose each sensor would be best suited to after establishing this. To do this I will have to set up a circuit shown above to produce a set of results calculating the resistance of the given sensor using the formula R = V/I as it varies with temperature. My circuit consists of two 1.5V batteries in series with an ammeter (which will give me my current reading), thermistor and a variable resistor, which I have placed in the circuit to act as a potential divider. The use of a potential divider is to...
