Instrumentation Task Sensor Project Introduction For this experiment I am going to investigate the variation of the resistance of a thermistor with different temperatures. The resistance will be tested at every 5 degrees, with a range from 90 C down to 5 C, and these results will be recorded. After recording the results, the experiment will be repeated at a total of 3 times, this is so we can get an average that should be correct and accurate. Plan: Sensor circuit The following below, are what are needed for me to complete my task: * One thermistor * Digital multi-meter with a setting to read resistance in Ohms to 2 decimal places The sensor circuit's purpose is to sense the change in temperature in a domestic water tank. For example it will be able to sense and recognise when the water is very close to boiling point and if it has dropped to close to freezing point....
