ABSTRACT

When measuring the temperature of an object, the temperature of the sensor is initially at a different value than that of the object, which in many cases would be the room temperature. Then the students put the sensor in contact with the object and wait for the temperature of the sensor to change and stabilize at the new temperature before making the reading. When designing a modern digital thermometer, a simple microcontroller would be used that is powerful enough to quickly complete this calculation without impacting the cost of the product, thus decreasing the time it takes to complete a measurement. A Wheatstone Bridge will be built incorporating a thermistor, data will be sampled and the initial readings will be used to calculate the final value by the extrapolation. The projected value will be compared to the actual final value.
