Sniffer4D HCHO Sensing Module: Add Fast Formaldehyde Detection to Your Sensing Setup

The Sniffer4D HCHO Sensing Module pairs solid-state electrochemistry with a sub-3-second response time, one of the fastest readings available anywhere in the Sniffer4D sensing lineup.

AIRINS has not published a specific application for this module, unlike most other Sniffer4D sensors, so this description focuses on its confirmed technical capability rather than a stated use case. It operates from -40 to 55 degrees Celsius and carries a 36 month rated service life.

Key Features and Benefits

  • Solid-state sensor: delivers precise formaldehyde readings with a fast response.
  • Detection limit of 1 ppm: flags low level formaldehyde events reliably.
  • Linear range to 100 ppm: spans trace through high concentration events.
  • Response under 3 seconds: keeps pace with fast moving inspection flights.
  • 0.1 ppm resolution: resolves fine formaldehyde concentration shifts with precision.
  • 36 month rated life: supports extended deployment across repeated missions.
  • Wide temperature tolerance: performs from -40 to 55 degrees across sites.
  • Wide humidity tolerance: functions reliably up to 95 percent RH conditions.
  • Single slot footprint: preserves flexibility for other modules in the array.

The HCHO Sensing Module gives Sniffer4D operators fast, precise formaldehyde readings in a single Base Unit slot. Its wide environmental tolerance keeps performance consistent across a broad range of deployment conditions.

Dronefly supplies the HCHO Sensing Module ready to pair with your Sniffer4D Nano 2 Plus Base Unit, tested for fast, precise formaldehyde readings. Order the HCHO Sensing Module through Dronefly and add formaldehyde detection to your sensing setup.

  • Detection principle: solid-state electrochemistry — a distinct sub-type from the standard electrochemical modules elsewhere in the batch
  • Linear range: 0 to 100 ppm
  • Limit of detection: 1 ppm
  • Accuracy: ±5% FS
  • Repeatability: <2%
  • Overall response time (t90): <3 seconds (0-50 ppm) — tied with TVOC for the fastest response in the batch
  • Display resolution: 0.1 ppm
  • On-chip proprietary temperature compensation algorithms
  • Warm-up time from cold start: ≈5 minutes
  • Estimated service life: >36 months
  • Operating temperature: -40 to 55°C — note: may require zero-point readjustment due to changes in operating temperature or working environment
  • Operating humidity: 15 to 95% RH (non-condensing)
  • 1x AIRINS Sniffer4D HCHO Sensing Module
How fast does this module respond to changing formaldehyde levels?

The module responds in under 3 seconds across its 0 to 50 ppm range, among the fastest response times in the entire Sniffer4D lineup, tied with the TVOC module. This suits situations where a quick reading matters more than a long dwell time. Its 1 ppm detection limit and 0.1 ppm resolution provide solid sensitivity at that speed.

What environmental conditions can this HCHO module handle?

The module operates from -40 to 55 degrees Celsius and up to 95 percent relative humidity, among the widest ranges in the Sniffer4D lineup. This supports deployment across a broad range of climates and site conditions. Dronefly can advise on additional considerations for extreme site conditions.

How long does this HCHO module last before it needs replacement?

The module carries an estimated service life of more than 36 months, among the longer-lasting modules in the Sniffer4D catalog. This makes it a dependable choice for programs running frequent flights over an extended period. Dronefly can advise on typical replacement planning based on your flight frequency.
