Adafruit PMSA003I Air Quality Breakout - STEMMA QT / Qwiic

Breathe easy, knowing that you can track and sense the quality of the air around you with this Adafruit PMSA003I Air Quality Breakout. This sensor is great for monitoring air quality in a compact plug-in format.

Unlike almost all other sensors that use UART interface, this one is an I2C interface, making it a great match for single-board Linux computers like Raspberry Pi or Arduino UNO using software serial.

It includes two SparkFun Qwiic compatible STEMMA QT connectors for the I2C bus, so no soldering is needed. Plug and play with other QT boards and sensors to add quick air quality sensing. (QT Cable not included)

This sensor uses laser scattering to radiate suspending particles in the air, then collects scattering light to calculate particle size and concentration.

The sensor outputs PM1.0, PM2.5, and PM10.0 concentrations in both standard and environmental units, particulate matter counts for different size bins, and checksum in binary format, updating once per second.

The breakout board includes a 5V mini boost circuit allowing power from 3.3V and 5V systems.

Available with compatible Arduino and CircuitPython libraries to read and interpret data easily.
