Sniffer-4D
DRONE-BASED AIR POLLUTANT MAPPING SYSTEM

Portable pollution mapping system
The Sniffer-4D offers high precision 3D air pollutant mapping using precision onboard gas sensors to detect eight pollutants simultaneously: VOCs, CH4, NO2, O3, CO, SO2, PM1.0, PM2.5 and PM10.
The Sniffer-4D is a small and lightweight unit (~500 g) that can be drone or vehicle mounted to allow for real-time data capture at various elevations. When used on a drone with programmable flights, an automated systematic grid of dense data can be collected.
