The Pico Air Monitoring Expansion is a HAT for Raspberry Pi Pico that measures suspended particulate matter (PM1.0, PM2.5, and PM10) in the air. It uses a PMSA003 digital laser dust sensor and includes an onboard 0.91″ OLED display for real-time readings.
The board communicates with the Pico via UART and also breaks out additional GPIO pins for connecting external peripherals and sensors.
Key Features
- PMSA003 Sensor – Digital laser dust sensor for particulate measurement
- PM Readings – Measures PM1.0, PM2.5, and PM10 concentrations
- 0.91″ OLED Display – Real-time air quality readings onboard
- UART Communication – Serial interface to Raspberry Pi Pico
- GPIO Breakout – Extra pins for external sensors and peripherals
- Open Source – Hardware and software available on GitHub
Specifications
- Sensor – PMSA003
- Particle Range – 0.3–1.0 µm, 1.0–2.5 µm, 2.5–10 µm
- Counting Efficiency – 50% @ 0.3 µm, 98% @ ≥0.5 µm
- Supply Voltage – 5 V DC
- Operating Current – 100 mA max
- Standby Current – ≤200 µA
- Response Time – ≤10 s
- Operating Temperature – 10 to 60 °C
- Dimensions – Approx. 92 × 68 mm
Ideal For
- Indoor and outdoor air quality monitoring
- Environmental sensing projects
- Portable particulate matter measurement
- STEM and maker projects with Raspberry Pi Pico
Note: Raspberry Pi Pico board is not included and must be purchased separately.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- Matter
- A smart home connectivity standard designed to let devices work across different ecosystems. It matters if you want a project to integrate more easily with platforms such as Apple Home, Google Home, or other Matter-compatible systems.
- OLED
- OLED stands for organic light-emitting diode, a display type where each pixel produces its own light. It matters because OLED screens are thin, high-contrast and easy to read for small status displays, but they can be more sensitive to image burn-in than some other display types.
- particulate matter
- Particulate matter means tiny particles suspended in the air, such as dust, smoke, pollen, or pollution. A sensor that measures it is useful for air-quality projects because particle levels can affect comfort and health.
- PM1.0
- PM1.0 refers to airborne particles with a diameter of about 1 micrometre or smaller. This size category matters because smaller particles can stay airborne longer and may come from sources such as smoke or combustion.
- PM10
- PM10 refers to airborne particles with a diameter of about 10 micrometres or smaller. It includes larger dust and pollen-like particles, so it is useful for detecting coarser airborne pollution.
- PM2.5
- PM2.5 refers to airborne particles with a diameter of about 2.5 micrometres or smaller. It is a common air-quality measurement because these fine particles can be breathed deep into the lungs.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
