About Sniffer Robotics

Sniffer Robotics, founded in 2016 by Arthur Mohr, Jr., David Barron, and Bob Dentzman, provides technology-enabled environmental services focused on methane emission detection and quantification. The company emerged from Mohr's hobby and a desire to automate environmental monitoring, a goal he pursued after a 30-year corporate career. Based in Ann Arbor, Michigan, the firm secured support from mentors at the Michigan Economic Development Corporation and participated in an Ann Arbor SPARK boot camp to refine its technology and business strategy.

The company's core offering is the SnifferDRONE™, a patented unmanned aerial system (UAS) that automates the traditionally labor-intensive and hazardous process of surface emissions monitoring. This system features a drone with a closed-loop methane detector and an air collection hose that samples near-ground air to precisely locate and measure methane leaks. The gathered data is then processed through its SnifferView™ GIS platform, providing clients with actionable insights for remediation. In December 2022, the U.S. EPA approved this automated technology for compliance monitoring, a first for the industry.

Sniffer Robotics operates on a "Technology as a Service" (TaaS) model, delivering drone-based aerial services, field technician support for manual inspections, and Esri GIS mapping solutions. Its primary market is the municipal solid waste (MSW) landfill industry—a major source of methane emissions—but its applications extend to renewable natural gas (RNG) facilities, mining, and agriculture. By identifying leak sources, the service also helps reduce landfill odors and increases gas capture for energy conversion. The company has expanded its operations across 28 states and has entered international markets, including Canada and South America, through a strategic partnership program.
