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

The M5Stack Air Quality v1.1 is a small, low-power air monitor using the Stamp-S3A for better efficiency and Wi-Fi performance. It has a 1.54” e-ink display and built-in sensors for PM1.0–PM10, temperature, humidity, VOCs, and CO₂. A 600mAh battery with sleep and wake functions supports long-term use, and data can be uploaded to Ezdata Cloud. With its magnetic base and LEGO-compatible mounting holes, it’s easy to set up in homes, schools, or industrial environments.

The M5Stack Air Quality v1.1 is an integrated low-power air quality monitoring device. Compared to the previous generation, the new version adopts the Stamp-S3A master control, with optimizations and improvements in overall power consumption and Wi-Fi antenna design.

The device features a 1.54′ e-ink screen with a 200×200 resolution. It is equipped with a multifunctional air quality sensor SEN55 and a CO2 sensor SCD40, capable of monitoring PM1.0, PM2.5, PM4, PM10 particulates, temperature, humidity, VOC, and CO2 concentration in the air.

The built-in 600mAh lithium battery and RTC low-power power management circuit allow it to achieve sleep and timed wake-up functions. The factory firmware supports uploading air quality data to the M5Stack Ezdata cloud platform, providing users with a convenient remote data viewing function.

The bottom structure offers LEGO-compatible mounting holes, a magnetic base, and 4 removable mounting lugs, supporting various mounting methods. Suitable for air monitoring in homes, schools, industrial sites, and medical environments.
