- Bosch BMV080 PM sensor is a revolutionary, tiny (4.4mm x 3mm x 20mm) sensor measuring particles up to 35cm in front of the device.
- The sensor's outward-facing design eliminates the need for a fan, potentially increasing its lifespan by preventing dust buildup.
- Testing revealed a significant warm-up delay (45-60 seconds) and sensitivity to obstructions within its 35cm detection zone.
- The sensor performed well under movement and bright light but showed sensitivity to strong vibrations.
- Temperature and rain simulations showed minimal impact on sensor performance, and it continued functioning with a glass screen protector.
- Comparative testing with a Palas Fidas 200 reference monitor showed the BMV080 underreported PM2.5 levels, especially at higher concentrations, due to its higher minimum detection size (0.5 µm vs. 0.18 µm).
- Despite some limitations, the BMV080 showed excellent correlation with the reference monitor at low to moderate concentrations, suggesting potential for accurate air quality monitoring in typical conditions.
- The sensor's unique design opens new possibilities for portable and outdoor air quality monitors, though its accuracy declines in environments with very high particle concentrations.
