This is an integrated low-power air quality monitoring kit that uses the M5StampS3A controller (based on an ESP32-S3 SoC) along with two air/environment sensors: the SEN55 (for particulates, VOC, temperature, humidity) and the SCD40 (for CO₂ concentration). It has a 1.54-inch e-ink display (200×200 px) for local read-outs, a built-in 600 mAh lithium battery with low-power / sleep and timed wakeup capabilities, plus a real-time clock (RTC) for scheduling. The design includes multiple mounting options (LEGO-compatible holes, a magnetic base, and removable lugs), a buzzer, buttons, and offers WiFi connectivity.
The Air Quality Kit v1.1 with M5StampS3A is a low-power device designed for long-term air monitoring. It features sensors for PM, VOCs, CO₂, temperature, and humidity, it supports cloud upload via Ezdata and offers flexible mounting options like LEGO holes, a magnetic base, and removable lugs. Suitable for homes, schools, hospitals, industrial areas, as well as research projects, distant monitoring, HVAC optimisation, and construction projects for dust suppression.
Previously, we have covered other ESP32-S3-based products, including the WiFIRCard, the Waveshare audio board, and many more. Feel free to check those out for your reference.
