Main PCB

• Main PCB embedded an ATMega32u4 and a CC3000
• You should build the firmware with User_firmware project
• Calibration Firmware project allows to calibrate the device and write value in eprom
• Firmware was be build with AtmelStudio 6.1 with bin size optimisations (debugger board AVRDragon)

Serial commands

• Here are the serial commands available in normal mode:
• 'e' shows the error state and the RAM usage
• 'm' shows the MAC address used for posts
• '-' deletes the wifi configuration

Sensor PCB

• Sensor PCB embedded a ATtiny, you should build AttinyI2CSlave project
• ATtiny communicate to MainPCB with this protocol
• Description of embedded sensor and query mode on this page

LED Patterns

###Air quality indications

• Red: air quality is kind of bad
• Orange: air quality is not so great
• Green: air quality is good

These colors are solid when everything is fine with the WiFi connection, and they glow slowly when their is a connection problem (cannot connect to AP, cannot connect to server,...).

Special states

• Blue-green, at startup: The Airboxlab is starting up.

• Pink (solid): there is a very big problem that requires servicing of the hardware.

• Blue (solid): WiFi has not been set up yet, please run the WifiConfigClient app.

• Blue (glowing slowly): during WiFi configuration.

• Off: when the LEDs have been turned off using the settings of the mobile app.

• Blue (solid, very weak): the LEDs have been turned off using the setting of the mobile app but there is a connection problem.
