Air Quality is an integrated low-power air quality monitoring device. It has a built-in multifunctional air quality sensor SEN55 and CO2 sensor SCD40, capable of monitoring PM1.0, PM2.5, PM4, PM10 particles, temperature, humidity, VOC, and CO2 concentration in the air. It uses the StampS3 main control, 8M Flash, and is equipped with a 1.54-inch e-ink display with a resolution of 200 x 200, which can display the final screen even after power-off. It has a built-in 600 mAh battery and RTC low-power power management circuit, enabling sleep and timed wake-up. The factory firmware defaults to uploading data to M5's EZDATA cloud platform, automatically generating monitoring pages for convenient remote cloud access for users. The bottom has LEGO mounting holes, magnetic adsorption, and 4 pluggable hanging ears, supporting various fixing methods. It is suitable for long-term online monitoring of air environments in homes, schools, industries, hospitals, and other fields.

Power On: You can wake up and start by pressing the "WAKE" button, or by the IRQ signal triggered by RTC timing. After triggering the wake-up signal, you need to set the hold(G46) pin to high level (1) in the program initialization to maintain the power supply, otherwise, the device will re-enter sleep mode. Power Off: When there is no external USB power supply, press the RST button to achieve it, or when there is no external USB power supply, set HOLD(GPIO46)=0 in the program to achieve power-off shutdown.
