Real-time data acquisition using Arduino and phyphox: Measuring the electrical power of solar panels in contexts of exposure to light in physics classroom

Abstract

An easy circuit for measuring the power of a solar panel in physics classroom by using the microcontroller Arduino will be introduced in this article. The measured data is transferred via Bluetooth to the smartphone app 'phyphox' where it is displayed graphically. The circuitry enables measuring the power of a solar panel in different situations of light intensity. Several model experiments for students will be described.
