About the Wearable air quality PCB

Wearable air quality is an open source PCB design by AMA-Labs, published on GitHub. It is a 2-layer board measuring 20.9 × 22.6 mm, with 10 components from 6 distinct parts.

Other key parts include the 110-407, SCD41 and MCP6L02x-xMS. By type, the board carries 5 ICs, 4 resistors and 1 connector.

It belongs with the sensors and wearables designs in this gallery.

From the project

A prototype Arduino air quality sensor designed to be worn at head level.

In sps30.h file make sure to do the following Comment out: #define INCLUDESOFTWARESERIAL 1

Change I2C length from 32 to 256>> #define I2C_LENGTH 256

Receieve buffer length change for non SMALLFOOTPRINT from 128 to 256: #else #define MAXRECVBUFLENGTH 256

Also install the ArduinoBLE library for the Arduino_BHY2. ----------------------
