id=\"description\"\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eAir 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-inch e-ink screen with a resolution of 200 x 200. 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.\u003c\/p\u003e\n\u003ch2 data-id=\"Features\"
