Sharp GP2Y1010AU0F Optical Dust Sensor - PM2.5/PM10 Detection

Sharp GP2Y1010AU0F Optical Dust Sensor enables accurate detection of airborne particulate matter using an infrared optical sensing method widely adopted in air purification and environmental monitoring systems. This compact particulate monitoring module measures dust density by detecting light scattered from particles passing through the sensing chamber. Stable analog output allows straightforward integration with microcontroller platforms for PM concentration analysis and indoor air quality evaluation. A rugged industrial housing, low power consumption, and reliable response characteristics make this optical particulate sensor suitable for continuous monitoring in smart buildings, HVAC systems, laboratory environments, and embedded environmental monitoring stations.

Dual‑Purpose Smoke and Dust Particle Detection

An infrared diode and phototransistor optical system detects light scattered by airborne particles inside the sensing chamber. Distinct scattering signatures allow differentiation between fine smoke particles around 0.3–1µm and larger dust particulates within the 1–10µm range. This optical particulate detection method improves monitoring accuracy in indoor air quality systems, filtration testing setups, and environmental sensing stations where both smoke and dust concentration changes require reliable measurement.

Linear Analog Signal for Precise Density Measurement

The particulate sensing module outputs a linear analog voltage proportional to dust density, delivering approximately 0.5V change for every 0.1mg/m³ concentration variation within a 0–3.5V signal range. This straightforward electrical interface enables easy integration with microcontroller ADC inputs for PM2.5 and PM10 estimation, environmental data logging, and smart ventilation control applications without complex communication protocols.

Compact Industrial Mechanical Design

A durable enclosure measuring 59×45×22mm houses the optical chamber, light source, and detection circuitry in a compact structure optimized for embedded systems. Reliable performance across operating temperatures from −10°C to 65°C allows deployment in indoor air monitoring devices, HVAC equipment, laboratory instruments, and industrial environments where consistent particulate measurement remains essential.

Low‑Power Continuous Monitoring

Typical current consumption of approximately 11mA with a maximum of 20mA enables energy‑efficient operation in battery‑powered air quality monitors and distributed environmental sensing networks. This efficient optical dust detection module supports long‑term monitoring tasks such as smart air purifier control, environmental dashboards, and IoT‑connected air quality stations without significant power overhead.

Typical deployment scenarios include smart air purifier feedback control, HVAC filter efficiency monitoring, workplace environmental compliance systems, and educational air quality monitoring platforms. The optical dust sensing unit also supports laboratory research setups, industrial particulate monitoring nodes, and building automation systems requiring reliable particulate density measurement.
