Built-in 4G/3G/EDGE/GPRS Connectivity
Operations in Sniffer4D have been greatly simplified,
deliverying improved user experience and much shortened learning time.
Designed for Simplicity
Up to 9 Parameters at a Time | Verified Data Quality | Cellular Connectivity | Plug & Play | Front & Back Warning Lights
Ultra-short Warm-up Time | Expansion Ports | API | OTA Update
Designed to be carried by drones & ground vehicles
Captures geo-referenced & time-stamped gas & particle concentrations
Real-time data transmission via LTE networks
Multi-gas Detection Hardware
* You can upgrade your Sniffer4D V1 into Sniffer4D V2
Negligible Warm-up Time
When Sniffer4D disconnects from power, it automatically enters "dormant mode*", in which the most crucial sensing components still remain working. Therefore, when Sniffer4D is powered up, almost no more warm-up time is needed for the sensors, helping users to race against time.
*Only available for certain sensing modules.
Sniffer4D Mapper visualizes and analyzes data in real time, provides intuitive information (e.g. 2D/3D pollution distribution, PDF mission reports) for decision makers.

Verified Data Quality
Flexible & Easy Calibration
Every Sniffer4D is factory calibrated before shipped out. We recommend re-calibrating the device every 6 months.
There are generally 3 ways to calibrate Sniffer4D.
Compare long-term datasets from Sniffer4D and a local reference monitoring station (placed at the same location) to determine the calibration parameters.
1. Data Learning
2. Calibrating Gas
Inject calibrating gases with known concentrations to determine the calibration parameters.
3. Quick Adjustment
Use local AQI information to roughly
determine the calibration parameters.
