Sniffer4D Nano 2 Plus: Standardize Airborne Gas Detection Across Your UAS Fleet
Sniffer4D Nano 2 Plus gives fleet programs a single modular gas detection architecture for the DJI Matrice 4 series, Matrice 400, Matrice 4E and 4T, and Matrice 350 and 300, built to standardize airborne hazard detection across every aircraft in a program. Two Base Unit configurations anchor the platform, extended through eleven interchangeable sensing modules spanning particulates, combustion gases, industrial gases, odor, and volatile organic compounds.
Programs choose between a Multi-Gas Base Unit with five reconfigurable slots or a standalone Methane Unit built around dedicated laser sensing, then standardize integration kits and connectivity accessories across the fleet. Because every configuration shares the same core hardware, scaling from a pipeline survey program to a multi-site HAZMAT response means adding modules, not qualifying new platforms.
Multi-Gas Base Unit and Methane Unit: Standardizing Your Fleet's Configuration
- Multi-Gas Base Unit: five internal module slots, senses up to six gas parameters simultaneously depending on module selection, native E-Port connection to the Matrice 4D and 4TD, extends to the Matrice 400, 4E and 4T, and 350 and 300 through separately sold integration kits.
- Methane Unit: standalone Multi-Pass TDLAS configuration built for dedicated methane screening, 200 ppb limit of detection, contact-based sampling rather than remote sensing, cannot pair with other sensing modules in the same housing.

Sniffer4D Nano 2 Plus Specifications for Fleet Wide Deployment
Every Base Unit configuration shares identical physical specifications across a fleet, which simplifies spare parts planning and crew training: housing smaller than 110 by 76 by 80 millimeters, weight of roughly 8.5 ounces (240 grams), an IP55 rating, and a built-in temperature, humidity, and pressure sensor active regardless of installed module. Power draws from the aircraft's E-Port directly or a 5 to 24 volt, 2 amp maximum external source, with USB-C limited to power delivery only.
Every unit includes a 32GB MicroSD card for local CSV logging, and encrypted 1Hz transmission paired with a 12-hour offline buffer keeps fleet wide data intact through connectivity gaps. Six status LEDs standardize diagnostics across every deployed unit, and swarm support lets one team monitor multiple aircraft from a single terminal.
Response times and detection limits shift by sensing module, from sub-3-second readings on TVOC and HCHO to roughly 2-minute warm-up on several electrochemical modules, a variance worth building into fleet wide flight procedures.

AIRINS.ai, DJI Pilot 2, and FlightHub 2 Integration for Fleet Operations
Every Sniffer4D Nano 2 Plus unit connects to the DJI ecosystem through DJI Pilot 2, which streams live sensor data and payload control from the DJI remote controller, and DJI FlightHub 2, which centralizes monitoring and control across a fleet, including an On-Premises version for programs with stricter data handling needs. Full DJI Payload SDK support underlies both integrations, so the Sniffer4D system operates as a native accessory across every airframe in a fleet rather than a bolted-on addition. AIRINS.ai ships included with every unit under a perpetual main-account license, covering point cloud, hex grid, and heatmap visualization, automated geofenced missions, PDF and DOCX reporting, and MQTT forwarding into third-party GIS or SCADA systems. Programs needing additional user access beyond the main account can add a separate sub-account, and fleets running multiple units can layer AIRINS.ai's swarm support on top of FlightHub 2's fleet-level control for one unified operational picture.
Standardizing Your Sniffer4D Nano 2 Plus Configuration Across a Fleet
- Start with your program's target gas list: standardize sensing modules to the parameters every mission requires before scaling Base Unit orders.
- Confirm airframe coverage across your fleet: native E-Port deployment covers the Matrice 4D and 4TD, while the Matrice 400, 4E and 4T, and 350 and 300 require a separately sold integration kit.
- Decide between combined and independent gas readings fleet wide: standardize the O3+NO2 and NO2 modules together where isolating ozone matters.
- Plan slot capacity across every unit: the Multi-Gas Base Unit holds up to five modules, while TSP/PM 100 and the Methane Unit each require a dedicated, standalone Base Unit.
- Budget for connectivity across the fleet: a Global SIM Card or existing SIM with cellular data is required for real-time transmission.
- Consider fleet branding needs: Top Surface Logo Customization is available for programs that want unit-level identification.
The Sniffer4D Nano 2 Plus platform gives fleet programs one hardware foundation for airborne gas and particulate detection instead of a different device per parameter across the fleet. Modular detection, encrypted data continuity, and included software let one architecture scale from a single aircraft to a full sensing program.
Dronefly supplies the full Sniffer4D Nano 2 Plus lineup, from Base Units through every sensing module and integration kit, ready to standardize across your fleet. As your dedicated drone partner, we help programs plan module and kit combinations that scale with the mission.

Frequently Asked Questions
What's the difference between the Multi-Gas Base Unit and the Methane Unit across a fleet?
The Multi-Gas Base Unit has five reconfigurable slots and can standardize up to five sensing modules per aircraft, letting fleets combine parameters like particulate matter, CO, and NO2 on a single flight. The Methane Unit is a fixed, single-purpose configuration built around Multi-Pass TDLAS laser sensing, standardized entirely around methane and unable to accept any other module. Programs building multi-parameter capability should standardize on the Multi-Gas Base Unit, while programs dedicated to methane screening should standardize on the Methane Unit. Some fleets run both configurations side by side on platforms like the Matrice 400.
Can a fleet combine multiple sensing modules on one Base Unit?
Yes, on the Multi-Gas Base Unit, which holds up to five modules simultaneously across its five internal slots. Two configurations are exceptions worth standardizing around separately: the TSP/PM 100 module occupies all five slots as a standalone build, and the Methane Unit is a fixed configuration that cannot accept any other module. Dronefly can help you plan a standardized module combination across every unit in your fleet.
Which Matrice airframes does the Sniffer4D Nano 2 Plus support across a mixed fleet?
The platform connects natively to the DJI Matrice 4D and 4TD through the aircraft's E-Port, with mounting hardware included. The Matrice 400, Matrice 4E and 4T, and Matrice 350 and 300 are supported through separately sold integration kits built for each airframe. Dronefly can confirm kit compatibility for every aircraft type in your fleet before you order.
Does every unit in a fleet need its own SIM card?
Yes, since each unit's LTE connectivity requires its own SIM. Dronefly offers a Global SIM Card with 1-year validity and 2GB of cellular data per unit, with a same-cost top-up option for an additional 2GB. Fleets can also provide their own SIM cards if standardizing on an existing carrier data plan.
Is AIRINS.ai software included across every unit in a fleet?
Yes, every Sniffer4D Nano 2 Plus unit includes a perpetual main-account license for AIRINS.ai at no recurring cost, so fleets don't need to budget a per-unit software subscription. Programs needing additional user access beyond the main account can add a separate sub-account. This keeps software licensing standardized and predictable as a fleet scales.
