Sniffer4D detecteur multigaz

Captures spatial distributions of gases and particles

Generates 2D/3D concentration maps in real time

Significantly improves work efficiency and reduces risks and costs

Sniffer4D Mapper – Data visualisation and analysis software

Sniffer4D Mapper visualises and analyses Sniffer4D data in real time, providing intuitive information (e.g. 2D/3D pollution distribution, PDF mission reports) for decision makers.

Air and ground vehicle integration options

Sniffer4D V2 integration kits are available for commonly used drones (DJI Mavic 2 and 3, Matrice 200/210/300/600, Autel Evo II) and land vehicles (car, utility).

These help you easily integrate your Sniffer4D V2 with most air and ground platforms for accurate air quality measurements and analysis.

Optional gas sampling module

Start or stop gas sampling via the DJI Pilot or Sniffer4D Mapper application. Adaptable to gas sampling bags of different capacities.

Automatic shutdown when the bag is full. Easy integration with DJI M300RTK. Plug & play.

Air and ground vehicle integration options

Turn any ground vehicle into an air pollution detection and mapping platform.


Non-destructive instant installation

No drilling or wiring is required. Mounting or dismounting can be done by one person in 15 seconds. Compatible with almost all land vehicles, including vans, buses and taxis.


High level of integration

The Sniffer4D V2 ground vehicle integration kit seamlessly integrates Sniffer4D, pump, battery system, and external GNSS module into a single device that can operate independently. Simple operations minimise the cost of training while avoiding operating errors.


Individual operation

Only one team is required for system installation and data collection, reducing the overall cost of obtaining hyperlocal information. Ultra-high spatial resolution. The Sniffer4D records data at 1Hz. Theoretical spatial resolution is up to 5 ~ 22 m at normal driving speed (20 ~ 80 km/h).


Real-time data transmission

Sniffer4D V2 transmits data via a cellular network with unlimited range. You can view the data in real time from anywhere.
