Abstract: This article presents the design and fabrication of an infrared power meter, based on an Arduino Nano and an MLX90614 sensor, intended to be used by school students to carry out the required practical investigating the emission of infrared radiation from different surfaces using a Leslie cube. Results of testing demonstrate that when the Leslie cube is at a temperature of 81 ∘C, the matt black surface emits 497 W m−2, while the shiny metal surface emits only 57 W m−2. With a low material cost of around $40 and straightforward assembly, this device offers a practical solution for schools. Additionally, it can be easily adapted for other purposes, such as temperature data logging.
