Unmanned aerial vehicles (UAVs) now have a new system to measure CO2 levels accurately. The system uses a lightweight sensor and can be easily integrated into different platforms. Tests show it can measure CO2 changes quickly and accurately, even in changing temperatures and pressures. In field tests, it was found to be precise and reliable compared to a standard instrument. This system can help track CO2 emissions and how they spread over time and space, making it valuable for monitoring air quality.
