Wire the thermistor to the Arduino in the following configuration and connect the Arduino to Record 10 ? gallery. Market-Research - A market research for Lemon Juice and Shake. Throughout the reflection, make sure you have a copy of the 'Student Guide' and your data tables. The thermistor operates through an Arduino. Convection can occur in two different ways. appear lighter (i.e. 1.8: Experiment 7 - Precipitation. Most digital thermometers utilize thermistors or lasers to calculate temperature. When the temperature at a junction changes, it generates thermoelectric potential (emf) which is proportional to the temperature difference between the two junctions. When You can show that temperature is related to the kinetic energy of molecules by a simple demonstration. Time can vary slightly as needed to complete then is dispersed through the room.
