The industry's best available solution for detecting land-based methane leaks and quantifying emissions.

  • An integrated emissions monitoring system with hardware and software specifically designed for the application.

  • Methane concentrations in parts per million (1-100% ppm).

  • Laser guided "terrain hugging" and patented "hozzle" enables air samples collected at ground surface.

  • Better process control of emissions monitoring through pre-programmed flight paths and objective data collection.

  • Analytics from data including temporal gas studies, emissions quantification (estimated gas flux), & operational KPIs.

  • Versatile: useful for US EPA compliance, or emission studies.

  • >90% accurate at identifying leak sources.

  • 50% faster than manual inspection for large terrestrial applications.

The patented* SnifferDRONE is an unmanned aerial system (UAS) providing the landfill, natural gas pipeline, biomass, and related markets, an alternative to the archaic and manual method for detecting methane at ground surfaces as described in our emissions monitoring page

The SnifferDRONE UAS consists of a package, designed and built by Sniffer Robotics, added to a commercially available unmanned aerial vehicle (drone). The system consists of a methane detector, flexible hose and weighted nozzle ("hozzle"), laser guided system to aid the terrain hugging capabilities, and software for flight planning, flight control, and data management.  During flight, the system collects air samples, measures the methane concentration, and pushes leak location data (based on a minimum ppm threshold and their GPS coordinates) to the Sniffer Field Ops mobile app allowing field technicians and site personnel the ability to quickly and efficiently inspect leak locations and manually verify if required.

Safer, more effective, and more efficient, at finding land-based methane leaks.


Are you a site owner interested in receiving a demonstration of the SnifferDRONE for your application? Sniffer performs work throughout the US and welcomes the opportunity to demonstrate the value of the SnifferDRONE UAS for compliance or study purposes. Please use the contact page to provide information about your application. We will contact you shortly thereafter to discuss your application. Thank you.

Are you interested in purchasing the SnifferDRONE for your own use? Sniffer Robotics' business model in the United States is to offer emissions monitoring services using the SnifferDRONE. Internationally we have received considerable interest from companies interested in using the SnifferDRONE for their own use - either on their own or sites, or as a service partner who will offer emissions monitoring services to their customers. If you are interested in discussing this possibility, we welcome the opportunity to talk with you about partnering. Please send an email to with details of your thoughts for evaluation.
