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


The patented* SnifferDRONE is an unmanned aerial system (UAS) providing the solid waste (landfill), natural gas pipeline, and related industries an alternative to the archaic, manual method for detecting methane at ground surfaces.  The method to identify methane gas for land-based applications is referred to as "Surface Emissions Monitoring" (SEM).  We provide an alternative means for SEM using the SnifferDRONE.

The SnifferDRONE features a closed-path methane detector onboard an unmanned aerial vehicle (UAV - drone).  A gas collection hose with a weighted air inlet nozzle is suspended from the drone to collect gas samples at the ground surface during flight operations. 


The air inlet nozzle's position at the ground is assured by the drone's active "terrain hugging" technology.  Terrain hugging is accomplished via an onboard laser system that actively monitors the distance between the ground and the drone, and


adjusts the drone's altitude autonomously to maintain the pre-determined distance throughout the flight.  This feature ensures the air inlet nozzle travels along the ground where air samples are collected. The system is able to collect at-surface methane emissions data over a variety of surfaces including geosynthetics, snow, and dense vegetation.


Methane concentration levels are reported in parts per million (ppm) with locational data that accurately and precisely reports leak locations and their sources.


The SnifferDRONE is used by customers to obtain greater insight of methane emissions than what is possible with current industry practice.  The information attained is useful in developing a more comprehensive approach to managing emissions.


Whether to gain further insights of methane emissions, or as part of a workflow compliant with regulations, the SnifferDRONE is a safe, efficient, and more effective tool for managing emissions.

Site owners are actively using the SnifferDRONE as a tool in obtain further insights as to the site's emissions.  The use of the SnifferDRONE may be performed in conjunction with quarterly surface emissions monitoring. 



The SnifferDRONE was designed to meet EPA requirements for surface emissions monitoring.  When used in conjunction with manual verification, this compliant 2-step approach provides a safer, more efficient, effective, and compliant solution for identifying methane exceedances.
