Instrumentation Project The aim of this experiment was to calibrate a thermistor and having done this, to estimate my body temperature. This is a diagram to show the circuit that we created in order to complete the aim. The thermistor that I used was a positive coefficient thermistor, meaning that the resistance increases as the temperature increases, this then leads to an increase in voltage. This circuit has created a potential divider. Two resistors in series divide the voltage across a circuit and form a potential divider. The output voltage is proportional to the input voltage, which is determined by the resistance. This is because of the following equation: V out = Vs x R1 (R1 + R2) This can be shown in the following examples, where the voltage supply is 5V and the fixed resistor (R2) is 100 ohms, R1 varies. In the first instance, it is 70 Ohms and...
