Summary
Track future evaluation and possible support for the DFRobot SEN0470 sulfur dioxide sensor (SO2, 0-20 ppm).
Aura currently supports the DFRobot SEN0466 for CO and is expanding support for related DFRobot calibrated electrochemical I2C/UART gas sensors. SEN0470 belongs to the same sensor family, so it is a reasonable future extension to evaluate.
Official reference from DFRobot:

Proposed scope
- Detect and initialize
SEN0470 cleanly without affecting existing supported sensors.
- Read and validate
SO2 concentration correctly.
- Expose the value through MQTT / Home Assistant discovery.
- Decide how
SO2 should appear in the local UI and web dashboard.
- Handle warmup, unavailable, and sensor-fault states cleanly.
- Document supported wiring, units, range, and limitations.
- Add tests where practical for shared protocol/parsing logic.
Testers wanted
I need testers with real SEN0470 hardware to help validate this once prototype support exists.
Useful tester feedback would include:
- detection and startup behavior
- warmup timing and stability
- expected units / scaling
- disconnect and reconnect behavior
- MQTT / Home Assistant output validation
- any real-world sanity checks for
SO2 readings
If you own a SEN0470 and are willing to test pre-release firmware, please comment here.
Notes
This is a future enhancement request.
No ETA yet.
