Description The Air Quality Kit is a low-power environmental monitor built around M5StampS3. It combines a compact E-Ink interface, onboard battery power, wireless connectivity, and the SEN55 SCD40 sensor combination for indoor air monitoring. As a M5StampS3 air monitor, it measures PM1.0, PM2.5, PM4, PM10, temperature, humidity, VOC, and CO2 concentration in one device. The Air Quality Kit uses a 1.54-inch 200 x 200 E-Ink display, so readings remain visible with very low power demand. A 600mAh lithium battery, RTC timer wake-up, and EZDATA cloud support make the M5StampS3 air monitor suitable for long-term online monitoring where quick installation and remote data access matter. The bottom structure includes LEGO mounting holes, magnets, and four detachable mounting ears. This makes the Air Quality Kit practical for homes, classrooms, laboratories, industrial sites, medical facilities, HVAC checks, and construction-site monitoring. The SEN55 SCD40 sensor set gives builders particulate, gas, temperature, humidity, and CO2 data without combining separate modules. Features Integrated air sensing: the SEN55 SCD40 sensor combination measures PM1.0, PM2.5, PM4, PM10, temperature, humidity, VOC, and CO2. M5StampS3 control: the M5StampS3 air monitor uses an ESP32-S3FN8 dual-core processor with 8MB Flash and 2.4 GHz Wi-Fi. Low-power display: the Air Quality Kit includes a 1.54-inch 200 x 200 E-Ink display that can retain the last image. Battery and RTC: 600mAh battery power and RTC timer wake-up support low-power monitoring cycles. Cloud-ready workflow: factory firmware can upload data to M5Stack EZDATA for convenient remote viewing. Flexible mounting: LEGO holes, magnetic base, and four M3 detachable mounting ears help the device fit different installation sites. Development platforms: UiFlow2, Arduino IDE, ESP-IDF, and PlatformIO are supported. Compact Monitoring Node The M5StampS3 air monitor format keeps sensing, display, power, mounting, and cloud reporting in a single enclosure. For rapid environmental deployments, the Air Quality Kit reduces wiring work while the SEN55 SCD40 sensor pair covers the most common indoor air-quality indicators. The SEN55 SCD40 sensor setup is also useful when teams need one compact reference node.

Classrooms and schools: use the M5StampS3 air monitor to track CO2 and particulate changes during the day. Industrial sites: the SEN55 SCD40 sensor readings help compare particulate and gas trends near work areas. Medical facilities: monitor local environmental indicators in protected indoor spaces. Research laboratories: log air-quality values and view remote data through EZDATA workflows. HVAC optimization: use the Air Quality Kit to observe how ventilation affects CO2, humidity, VOC, and PM readings. Construction sites: deploy a portable M5StampS3 air monitor for temporary environmental checks. Product List 1 Air Quality 1 User Manual Other Content Sensor Coverage The SEN55 SCD40 sensor combination lets one compact node collect particulate, VOC, humidity, temperature, and CO2 data. This helps the Air Quality Kit report a broader environmental picture than a single PM-only device. Mounting and Wiring The M5StampS3 air monitor includes a magnetic base, LEGO-compatible holes, and detachable mounting ears. The Grove interface gives the Air Quality Kit an expansion path for custom installations. User Manual and Circuit Reference Use the manual and schematic when planning firmware changes, enclosure mounting, power behavior, or I2C integration around the SEN55 SCD40 sensor. Resources M5Stack product documentation M5Unified library FAQ What does the Air Quality Kit measure? The Air Quality Kit measures PM1.0, PM2.5, PM4, PM10, temperature, humidity, VOC, and CO2 concentration through the SEN55 SCD40 sensor set. Why use an E-Ink display? The E-Ink display helps the M5StampS3 air monitor keep readings visible with low power use, which is useful for battery-supported monitoring. Can it upload data remotely? Yes. Factory firmware supports M5Stack EZDATA cloud upload, so the Air Quality Kit can provide convenient remote viewing after setup. How can it be mounted? The device supports LEGO holes, a magnetic base, and four detachable mounting ears. These options make the M5StampS3 air monitor easy to install in temporary or fixed positions.
