Unmanned Aerial Vehicular System for Greenhouse Gas Measurement and Automatic Landing

This paper presents a reliable and low cost greenhouse gas measurement system. The system mainly consists of an unmanned aerial vehicle (UAV), a set of calibrated sensors, a wireless system, and a microcontroller. The system can measure the concentration of greenhouse gases namely carbon dioxide (CO 2 ), methane (CH 4 ), and ozone (O 3 ) at different altitudes. It can also measure temperature, humidity, and atmospheric pressure. The system is able to send data to a remote monitoring station. The UAV is equipped with image processing based navigation and landing system so that it can land autonomously on a designated place. To ensure safe landing the system uses a specially designed parachute. This paper also presents some data generated by the system.
