Efflux is the companion app for Thearen flux chambers. Connect over Bluetooth or WiFi, watch CO₂ and CH₄ flux build in real time, and run GPS-tagged sampling campaigns that turn into interpolated flux maps — on your phone, your desktop, or straight from the browser.
What it does
Real-time CO₂ and CH₄ flux with slope and R², plus min/max/mean for pressure, temperature and humidity — updated as the chamber fills.
Pair a Thearen IRB flux chamber over BLE or discover it on the local network via mDNS. Add an accumulation chamber and GPS receiver as needed.
Plan a survey of sampling points, then see your real acquisitions rendered as an IDW, Kriging or contour flux surface — with wayfinding to the next point.
Geotag every run from the device GPS or an external receiver (Garmin eTrex / GLO 2), and reconcile tracks after the fact for higher accuracy.
One app on Android, Windows, Linux and the browser. Export acquisitions to XLSX or a portable .effluxdb backup you can move between devices.
Warm-up, close, acquire, open and circuit-clean — stepped through for you, with the screen kept awake and auto-reconnect if a link drops.
.AppImage runs on any distro; or the .deb for Debian/Ubuntu, the .rpm for Fedora/RHEL.127.0.0.1 — no account, no configuration.
