Embedded and hobbyist electronics specialist M5Stack has launched a next-generation air high quality sensor system, now constructed across the firm’s Stamp-S3A Espressif ESP32-S3 microcontroller module and that includes an built-in 1.54″ ePaper show.
“Air High quality v1.1 is an built-in low-power air high quality monitoring system. In comparison with the earlier era, the brand new model adopts the Stamp-S3A grasp management, with optimizations and enhancements in total energy consumption and Wi-Fi antenna design,” the corporate says of the redesigned {hardware}. “The manufacturing unit firmware helps importing air high quality knowledge to the M5Stack Ezdata cloud platform, offering customers with a handy distant knowledge viewing perform.”

The sensor system, delivered to our consideration by CNX Software program, is available in a case that includes screw, magnetic, and LEGO-compatible mounting choices and is constructed across the M5Stack Stamp-S3A — a compact breadboard-friendly growth board that includes the identical Espressif ESP32-S3 microcontroller as the sooner Stamp-S3, giving it two 32-bit Tensilica Xtensa LX7 microcontroller cores operating at as much as 240MHz plus 8MB of on-module flash reminiscence, however with an improved antenna design for higher wi-fi reception.
To this, M5Stack has added the Sensirion SEN55 and SCD40 sensors — delivering high-accuracy readings for particulate matter in PM1.0, PM2.5, PM4, and PM10 measurements, risky natural compounds (VOCs), temperature, humidity, and carbon dioxide focus. There’s an on-board real-time clock, and in addition to the aforementioned firmware for mechanically streaming knowledge to a cloud dashboard there is a 1.54″ 200×200 ePaper show — designed for a low energy draw to get as a lot life out of the bundled 600mAh battery as doable.

Different options of the bundle embody two user-addressable buttons, plus bodily energy and reset buttons, a passive buzzer for audible alerts, and a Grove-compatible interface for solder-free growth to extra sensors or different add-on {hardware}.
The redesigned package is now obtainable to order on the M5Stack retailer, priced at $89.90 plus delivery.
