Plantower PMSA003-A PM2.5 Laser Particle Concentration Sensor, UART, 0~500 µg/m³, 5V
The Plantower PMSA003-A is a digital laser Particle concentration sensor with UART output, designed for precise measurement of PM2.5 and other airborne particulates from 0.3 to 10 µm. Operating at 5V, it provides real-time concentration data for integration with Arduino, Raspberry Pi, ESP32, and other microcontroller-based air quality monitoring systems.
Features
- High-sensitivity laser scattering principle detects particles as small as 0.3 µm.
- Digital UART interface provides real-time PM2.5 concentration data (0-500 µg/m³).
- Low power consumption with active (<100 mA) and standby (<200 µA) modes.
- Robust six-sided EMI shielding ensures stable operation in electrically noisy environments.
- Designed for long-term reliability with an MTTF (Mean Time To Failure) ≥3 years.

The PMSA003-A utilizes a laser scattering principle to count and size airborne particles. An internal fan draws air through the sensing chamber, where a laser illuminates particles. A photodetector measures the scattered light intensity, which is processed by an onboard microcontroller to calculate Particle concentration by size bin, outputting standardized digital data via UART.
Engineered for continuous environmental monitoring, the sensor operates reliably across a wide temperature range of -10°C to +60°C and 0-99% relative humidity. Its advanced anti-interference design, featuring six-sided electromagnetic shielding, guarantees signal integrity and measurement accuracy in demanding industrial or urban settings, making it suitable for long-term deployment in air purifiers, HVAC systems, and portable monitoring stations.
