M5Stack Air Quality Kit v1.1 with M5StampS3A (SEN55, SCD40)

The Air Quality Kit v1.1 with M5StampS3A is an integrated, low-power air quality monitoring solution designed for precise, real-time environmental data collection. Compared to the previous generation, this upgraded version adopts the Stamp-S3A master controller with optimized power consumption and enhanced Wi-Fi antenna design for stronger connectivity.

Equipped with the Sensirion SEN55 multifunctional air quality sensor and SCD40 CO₂ sensor, it can simultaneously monitor PM1.0, PM2.5, PM4, PM10 particulates, temperature, humidity, VOC, and CO₂ concentration. The 1.54-inch e-ink display (200×200 resolution) ensures clear, low-power data visualization, while the 600mAh lithium battery and RTC low-power management enable sleep mode and scheduled wake-up for extended operation.

Out of the box, the factory firmware supports EZDATA cloud platform integration, allowing remote monitoring from anywhere. The versatile mounting system—LEGO-compatible holes, magnetic base, and removable lugs—makes it suitable for homes, schools, industrial sites, and medical environments.
