Sparkfun Particulate Matter Sensor - SPS30 | SEN-15103

Description:

The SPS30 is a compact particulate matter sensor that utilizes laser scattering technology to detect a wide range of particle sizes. Manufactured by Sensirion, this sensor is unique because it provides "MC" (Mass Concentration) and "NC" (Number Concentration) for various particle categories including PM1.0, PM2.5, PM4, and PM10.

A standout feature of the SPS30 is its proprietary contamination-resistance technology. Unlike most PM sensors that degrade as dust accumulates on the optics, the SPS30 features an internal fan and a specialized airflow path that prevents dust buildup. It also includes an automated self-cleaning routine, ensuring a service life of more than 10 years in continuous operation. This makes it the preferred choice for professional environmental sensing stations and smart city infrastructure.

Features:

Mass & Number Concentration: Measures both the mass (µg/m³) and the actual count of particles per cubic centimeter.

Multi-Category Sensing: Provides data for PM1.0, PM2.5, PM4, and PM10, allowing for detailed air quality analysis.

Laser-Based Precision: Utilizes advanced laser scattering for higher resolution and accuracy compared to LED-based sensors.

Self-Cleaning Mechanism: Features an automated fan-driven cleaning cycle to maintain optical clarity over years of use.

Dual Interface: Supports both I2C and UART (serial) communication protocols, making it compatible with Arduino, ESP32, and Raspberry Pi.

High Durability: Rated for continuous 24/7 operation with minimal drift over the sensor's lifetime.
