Fermion: BMV080 PM2.5 Air Quality Sensor

SKU: SEN0663

Fermion BMV080 PM2.5 Air Quality Sensor uses Bosch BMV080 (world’s smallest particulate sensor). It features ±10μg/m³ accuracy, 0-1000μg/m³ range, 24×20mm size, 6μA power, 10-year lifespan, and fanless design (laser-based optical counting). No fan avoids noise/dust issues (unlike traditional 1-2y life sensors). Compact breakout board supports I2C/SPI; Arduino library included. Ideal for portable monitors, air purifiers, etc.
