The VoCS gas detector has been miniaturized and integrated into a pod payload for small UAVs, providing unprecedented mobility for gas detection. The device transmits gas detection imagery in real-time to a rear command center, enabling operators to conduct full facility inspections without entering industrial areas. This significantly improves inspection efficiency while ensuring operator safety. Alternatively, the UAV can be deployed from a mobile enforcement vehicle, with data displayed in real-time on the vehicle’s command screen, making it an powerful tool for environmental monitoring and compliance inspections.
