From the project

Root repository for AirMQ hardware project

AirMQ toolkit consists of main MCU and several sensor boards designed with common form factor in mind. Currently, particulate matter, radiation and electrochemical sensor boards are available.

MCU board includes advanced power circuitry which makes possible the use of reduced consumption modes while powering from batteries or solar panels. All ESP8266’s gpio pins are accessible with a separate 16-pin connector sharing pin numbering with most popular development boards.
