Imagine creating a gas sensor that can detect harmful gases like
carbon monoxide (CO) and carbon dioxide (CO2) in the air. In
this learning scenario, designed for 10 to 11-year-old students
with basic knowledge of electronics and programming, we
embark on a journey to build such a sensor using Arduino
technology.
The motivation behind this project is not just about creating a
gadget; it's about real-life problem-solving. The students are
inspired to measure these gases, not only for educational
purposes but also to make a positive impact on their
environment. The goal is simple: detect high gas concentrations,
signaling when safety measures such as wearing masks or
evacuating an area are necessary.
