## Description

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.
