Nowadays, an integration of the sensor-based technology to learning science is required in order to improve the quality of science teaching especially for the better physical measurement quality. The utilization of sensor technology embedded with ArduinoTM programming can handle the problem of the real-time data recording. For example, in a conventional time-dependent physics experiment conducted at schools, the students commonly input the data with the help of a ticker timer or a stopwatch manually. However, some physics experiments studying the time-dependent physical changes cannot be run well. In this case, the heat transfer phenomena including a conduction, a convection, and a radiation cannot be explored except we have the device to identify the time-dependent heat changes during the investigation. Thus, a novel educational lab kit investigating the heat transfer will be proposed. The time-dependent measurement employsMAX6675K temperature sensors-based ArduinoTM micro controller. The temperature changes at certain positions along a rod can be investigated while the rod is being heated. Interestingly, the result shows the good tendencies of time-dependent temperature changes due to the conduction phenomena. The effects of the cross-section area and the rod length will be explored. It is believed that this design is suitable for the students and the teachers to be implemented at school. © 2017 The Authors.
