Objective The challenging task that I have finalised and undertaken for this coursework is to build and test a sensor. I decided to build a sensor, which would automatically change the speed of a fan by using a thermistor. The main objective of the experiment was to monitor and record the voltage change as the temperature changes. Specifically, as predicting that when the temperature increases the voltage would increase and thus the fan speed would increase too, thus causing a cooling effect to the environment. Data Information Thermistors are thermally sensitive resistors and have, according to type, a negative (NTC), or positive (PTC) resistance/temperature coefficient. A thermistor is a type of resistor whose resistance changes significantly when its temperature changes. A negative temperature coefficient thermistor has a resistance that decreases with increase of temperature. This is the most common type. This is the type of resistor that I shall be evaluating and will...
