Gas & Air Quality Sensors

SKU: AF-4632 | Brand: Adafruit

The Adafruit PMSA003I Air Quality Breakout is a compact laser-scattering particulate matter sensor with an I2C interface — a significant advantage over the UART-based sensors that dominate this category. Simply connec...

SKU: AF-4829 | Brand: Adafruit

The Adafruit SGP40 is a next-generation MOX (metal-oxide) gas sensor from Sensirion for indoor air quality monitoring. Unlike its predecessor the SGP30, the SGP40 outputs a raw signal that is processed through Sensiri...

SKU: AF-3709 | Brand: Adafruit

The Adafruit SGP30 is a multi-pixel MOX (metal-oxide) gas sensor from Sensirion that measures Total Volatile Organic Compounds (TVOC) and equivalent CO2 (eCO2) for indoor air quality monitoring. With fully calibrated ...

SKU: AF-5964 | Brand: Adafruit

The Adafruit SEN54/SEN55 Adapter Breakout lets you quickly connect a Sensirion SEN5x environmental sensor node to any microcontroller or single-board computer via STEMMA QT / Qwiic — no soldering or breadboarding requ...

SKU: AF-5593 | Brand: Adafruit

The AGS02MA is a compact MOX-based TVOC (Total Volatile Organic Compounds) gas sensor with an I2C interface. It features a built-in ADC that outputs gas resistance and parts-per-billion (ppb) readings — higher ppb val...

SKU: AF-4505 | Brand: Adafruit

The PMSA003I is a compact particulate matter sensor that measures PM1.0, PM2.5, and PM10.0 concentrations using laser scattering. Unlike most PM sensors that use UART, this version features an I2C interface, making it...

SKU: AF-6512 | Brand: Adafruit

This compact breakout measures true ambient CO2 concentration using photoacoustic sensor technology, rather than estimating CO2 from VOC gas concentration. It reports CO2 in parts per million and also includes integra...
