Description

The PMS5303 sensor employs a laser diode and photodetector to implement Mie scattering theory, quantifying airborne particulate concentrations in real-time. It outputs digital Particle count data for three distinct size bins (0.3–1.0 µm, 1.0–2.5 µm, and 2.5–10 µm), which are algorithmically converted to mass concentration values (µg/m³). The module’s integrated fan ensures consistent airflow across the sensing chamber.

Designed for continuous sampling, the sensor provides serial data updates every second. Its robust six-sided metal shield protects the optical path from ambient light and external contamination, ensuring high signal integrity. The 5V power requirement and low standby current make it suitable for both line-powered and battery-operated air quality monitoring systems.

Key Features

  • High-precision laser scattering detection with 0.3 µm minimum Particle resolution.
  • Real-time serial output of PM1.0, PM2.5, and PM10 mass concentration data.
  • Patent-protected six-sided optical shielding for superior anti-interference performance.
  • Flexible mounting with customizable airflow inlet/outlet orientation.
  • Low-power architecture with <10 second warm-up and fast response time.
  • Wide effective measurement range from 0 to 500 µg/m³.
  • Durable construction with a metal housing for long-term environmental monitoring.
  • Simple integration via standard 5-pin connector (5V, GND, TX, RX, SET).

Applications

  • Indoor and outdoor air quality monitoring stations and data loggers.
  • HVAC system particulate filter efficiency and clog detection.
  • Portable personal air quality monitors and wearable environmental sensors.
  • Industrial workplace safety systems for dust and aerosol exposure monitoring.
  • Smart home and building automation for ventilation control based on PM levels.

Frequently Asked Questions

What is the output protocol and voltage level of the PMS5303 sensor?

The PMS5303 outputs data via a UART serial interface at 3.3V TTL logic levels. The default baud rate is 9600 bps, transmitting a structured data packet every second containing PM1.0, PM2.5, and PM10 concentration values in µg/m³. For use with 5V microcontrollers like Arduino Uno, a simple logic level converter or voltage divider on the RX line may be required.

What is the power requirement and current consumption?

The sensor requires a stable 5V DC power supply within the range of 4.5V to 5.5V. During active measurement with the fan running, it draws approximately 200 mA. It features a low-power standby mode where consumption drops to around 2 mA, which can be controlled via the SET pin for battery-powered applications.

How do I mount and orient the sensor for accurate readings?

For optimal performance, mount the sensor in a location with representative airflow, avoiding direct exposure to wind, rain, or condensation. The module's patented six-sided shield protects the optics, but the air inlet and outlet should remain unobstructed. The orientation can be customized; the sensing chamber and fan are designed to function in various positions.

Does the sensor require calibration or periodic maintenance?

The PMS5303 is factory-calibrated and typically does not require user calibration. However, for long-term accuracy, periodic cleaning of the external air inlet grille is recommended to prevent dust accumulation. The laser and photodetector are sealed within the shielded chamber, minimizing the need for internal maintenance under normal operating conditions.
