M5Stack Air Quality Kit V1.1 with SCD40 and SEN55

The Air Quality Kit V1.1 from M5Stack is an integrated air quality monitoring device with low power consumption and comprehensive sensors. The device is based on the Stamp-S3A Controller with ESP32-S3 processor and offers optimized energy efficiency and an improved WiFi antenna design compared to the previous version. A 1.54-inch E-Ink display with 200×200 pixels permanently shows the measurements, even when the device is off. The multifunctional SEN55 air quality sensor detects particulate matter (PM1.0, PM2.5, PM4, PM10), temperature, humidity, and volatile organic compounds. The SCD40 CO2 sensor measures carbon dioxide concentration precisely. An integrated 600 mAh battery and the RTC-based energy management allow for sleep and scheduled wake-up functions. The factory firmware supports uploading air quality data to the M5Stack Ezdata Cloud platform for convenient remote monitoring. Various mounting options such as mounting holes, magnetic base, and removable mounting flanges offer flexible installation possibilities.
