Sniffer4D O3+NO2 Sensing Module: Standardize Photochemical Oxidant Tracking Across Your Fleet

The Sniffer4D O3+NO2 Sensing Module brings standardized photochemical oxidant tracking to any Sniffer4D Nano 2 Plus Base Unit, reporting combined ozone and nitrogen dioxide levels through a single electrochemical sensor in one module slot.

Programs planning fleet wide gas coverage should account for this module's core tradeoff up front: it reports O3 and NO2 as one combined value, not two independent readings, so isolating ozone specifically requires standardizing a companion NO2 module across the same units. Fleets that only need a general oxidant indicator can deploy this module alone across every aircraft.

Key Features and Benefits

  • Electrochemical sensor: reports combined ozone and nitrogen dioxide oxidant readings together.
  • Detection limit of 10 ppb: flags low level oxidant events across sites.
  • Linear range to 11 ppm: spans trace through elevated oxidant concentrations reliably.
  • Response under 45 seconds: keeps pace with fast moving fleet flight schedules.
  • On-chip humidity correction: standardizes accuracy across a distributed sensor fleet.
  • 1 ppb resolution: resolves fine shifts in oxidant gas concentration data.
  • 24 month rated life: supports standardized deployment across a fleet's lifecycle.
  • Single slot footprint: adds oxidant sensing without reconfiguring the module array.
  • Operating humidity to 85% RH: performs across a wide range of sites.

The O3+NO2 Sensing Module gives fleet programs a standardized way to track photochemical oxidant levels across every deployed unit. Pairing it with a companion NO2 module where individual ozone data matters keeps fleet wide monitoring both flexible and consistent.

Fleet programs standardizing on photochemical oxidant tracking can source the O3+NO2 Sensing Module through Dronefly, ready to install across your Base Unit lineup. Order the O3+NO2 Sensing Module through Dronefly and add oxidant monitoring to your fleet's sensing capability.

Can this module report ozone and nitrogen dioxide as separate values across a fleet?

No, not by itself. Every unit running this module reports a single combined oxidant value, without distinguishing how much comes from ozone versus nitrogen dioxide. Fleets that need individual O3 data should standardize a companion NO2 module alongside this one across the same aircraft, since O3 is calculated as the combined reading minus the NO2 module's reading. Programs that only need a general oxidant indicator can run this module alone fleet wide.

How long does each unit need to warm up before a fleet mission?

Each module takes approximately 2 minutes to warm up from a cold start, which is worth building into standard pre-flight procedures across a fleet. Standardizing warm-up timing across every operator keeps data collection consistent from unit to unit. Dronefly can help you build this into a fleet wide operating checklist.

Does this sensor require periodic recalibration across a distributed fleet?

The published specifications list a sensitivity drift of -20 to -40 percent per year and a zero drift of 0 to 20 ppb per year, both under laboratory conditions, and note that zero-point readjustment may be needed after significant temperature or environment changes. We don't have a defined recalibration interval from AIRINS to share beyond those figures, so for fleet programs running long-term deployments, we'd recommend reaching out to Dronefly or AIRINS directly to establish a maintenance schedule.

What environmental range does this module support across multiple deployment sites?

The module operates from -30 to 40 degrees Celsius and 15 to 85 percent relative humidity, a narrower range than some other Sniffer4D modules. Fleet programs operating across varied climates should confirm this range fits every deployment site before standardizing on this module. The on-chip humidity correction algorithm helps maintain data quality within that range.

Does every aircraft in a fleet need its own Base Unit to run this module?

Yes. Each O3+NO2 Sensing Module installs into its own Sniffer4D Nano 2 Plus Base Unit, which connects natively to the Matrice 4D and 4TD, with integration kits available separately for the Matrice 400, Matrice 4E and 4T, and Matrice 350 and 300. Dronefly can help plan Base Unit and module procurement to keep your fleet's configuration standardized.
