Continuous methane monitoring for closed landfills.
Most closed landfills are checked a few times a year. Cairn Sensing places solar and battery-powered sensors across a site and reports around the clock over cellular, switching to satellite where there is no signal.
Now running free 90-day pilots with landfill operators in Washington.
What a site gets
- Sensors on what’s thereSolar and battery-powered units mount on the boundary gas probes a site already has. No trenching, no grid power.
- Always reportingReadings go out over cellular, switching to satellite where there is no signal.
- Threshold alertsAlerts arrive the moment a reading crosses your threshold, not at the next quarterly visit.
- ReportsCompliance reports generate in one click.
