The flame sensor is a module that detects the infrared (IR) radiation that comes from a fire 🔥, the Sun , and other sources of heat. Thanks to controller boards such as Arduino,
sensors are easy to use and affordable , which makes them very attractive as an educational resource. This lnstructable aims to bring teachers closer to the didactic use of low-cost sensors in the Physics class. We will offer examples of practical activities in which sensors are used as a tool to illustrate physical concepts, to show the relationship between magnitudes in a practical way, or to take measurements in laboratory activities.
