Sensirion SPS30 Laser Scattering PM Particle Sensor

Sensirion SPS30 Laser Scattering PM Particle Sensor

Specifications
Brand: Sensirion
Model: SPS30
Origin: Switzerland
Measurement Range: 0–1000 μg/m³ (mass concentration)
Output Particle Sizes: PM1.0 / PM2.5 / PM4 / PM10 (mass concentration), PM0.5 / PM1.0 / PM2.5 / PM4 / PM10 (particle number concentration #/cm³)
Accuracy: 0–100 μg/m³: ±10 μg/m³; 100–1000 μg/m³: ±10% of reading
Power Supply: 4.5–5.5 V (typical 5V)
Current: Average 55 mA; Peak 80 mA
Interface: I²C or UART (choose one, shared hardware pins)
Dimensions: 41 × 41 × 12 mm
Lifespan: >10 years (anti-contamination patented design)
Operating Temperature: -10℃ ~ 60℃
Humidity: 0–95% RH (non-condensing)

Principle: Laser light scattering method; built-in micro fan actively draws air, particles pass through laser beam and produce scattered light, detected by a photodiode. The chip algorithm outputs multi-range particle mass concentration and number concentration. Factory calibrated, no external calibration required.
