Welcome
Welcome to your own personal AIRKit!
This guide will help you assemble your AIRKit and give you
a glimpse into the effects of CO2.
With AIRKit, you will assemble your own CO2sensor and be
able to record the levels of carbon dioxide in the air around
you –wherever you may be!

Overview
Carbon Dioxide (CO2) is everywhere around us. It
is safe in low concentrations, however spending
long periods of time in higher levels may cause
long term health issues and affect our wellbeing.
In 2018, average atmospheric carbon dioxide
levels were 407ppm. This is the highest level in
800,000 years!
Measuring and becoming aware of the CO2levels
around us can help us avoid high CO2
concentrations, so we can live healthier lives.
With AIRKit, you will assemble your personal CO2
sensor and record the levels of CO2in the air
around you –wherever you may be!

Setup
Setup time required: 20 minutes
Additional materials:
•Scissors
•Pritt stick (or any other brand of glue)
Step 1 Prepare the case!
Cut the case cover (7) along the solid black lines.
Glue the cover to the outside of the AIRKit case (6).
Taking care, follow the scissor markings on the template
and cut out holes for the following: CO2sensor, LED screen.
Assemble the box by folding the printed ‘fold’ lines.
Make a hole on the back of the box, large enough to thread
the USB cable (11) through.

Step 2 Insert the brains, connect the nose
Cut the foam into five equal sized pieces. Save one of them
for later, take the other four and stick them to LCD screen
(4) and the CO2sensor (3).
Push the feet (12) through the holes on the microcontroller
board (2) stick it to the inside of the box.
Using the I2C cables (5) connect the microcontroller board
(2) to the CO2sensor (3) and the LCD Screen (4). The I2C
connectors only fit one way. Make sure you are connecting
them to the I2C ports on the board, not the UART - they are
labelled. Once everything is connected, place all the
components in the box.

Step 3 POOOOOWER!
Clip the 9V battery (8) to the battery connection cord (9) and
connect the battery connection cord to the power switch
(10).
Connect the power switch cable to the round jack barrel
power socket on the Microcontroller board (2).
Leave the 9V battery and power switch inside the box, you
can use the saved piece of foam to stick them to the box.

Step 4 Start measuring
Flip on the power switch (10). The LED Screen (4) will turn
on and the first reading will be displayed. There will also be
a green light on the microcontroller board (2).
If you wish to power the AIRKit for a long period of time,
connect the AIRKit to a USB power source by connecting
the USB-C cable to the micro controller board.
Close the box so that the CO2Sensor is exposed to your
surroundings.
Leave for 10 seconds to allow the sensor to settle and
display the first true value of your CO2exposure.
Enjoy and start experimenting!
