Description

Air Quality is a low-power, all-in-one air-quality monitoring device. It integrates the multifunctional air-quality sensor SEN55 and the CO₂ sensor SCD40, enabling the measurement of PM1.0, PM2.5, PM4, PM10 particulate matter, temperature, humidity, VOC, and CO₂ concentration. Powered by the StampS3 MCU with 8MB Flash, it features a 1.54-inch E-Ink display (200 × 200) that retains the last image even when power is off. A built-in 600 mAh battery together with an RTC low-power management circuit supports sleep and timer wake-up functions.

The factory firmware uploads data to M5’s EZDATA cloud platform and automatically generates a monitoring page, allowing convenient remote access for users. The bottom of the device provides LEGO mounting holes, magnets, and four detachable mounting ears for versatile installation. It is ideal for long-term online monitoring in environments such as homes, schools, industrial sites, and medical facilities.

Works great

The device works great. I have flashed ESPHome to it and am running that instead. It reports flawlessly to my Home Assistant setup. The only caveat here is that the temperature sensor (and humidity sensor as a consequence) is wildly inaccurate from sensor self-heating. It detects a temperature about 3 degrees warmer than what it actually is. Unfortunately it is almost impossible to reliably correct for this.

Gute Arbeit Danke

Works well, very easy setup

If you need to know what's going on with the air quality in a room, attic or under the sink, this is the device for you. I was impressed how easy it was to get started, it maybe took me 30 seconds. I'll certainly get a few more. (Battery could be bigger, but no complaints).

Works great in Home Assistant

I was able to install esphome to the AirQ and add to Home Assistant. Now I can monitor it there and track history, rather than rely on the little display, which only shows a snapshot.

Excellent sensors, would be more useful if integrated with home assistant

Excellent form factor, ok aesthetics, enough info in the diagram to be able to include it with ESPhome but does not have an official integration code/pathway, so you'll have to figure it out yourself, giving up some functions (battery charging and usage, display details, etc ...)
