SETTING UP
Whether you are using a Raspberry Pi 400 or a Raspberry Pi 2, 3 or 4, make sure
that the Raspberry Pi is shutdown and powered off before you connect the Air
Quality Sensor.
The Air Quality Sensor will display the eCO2 readings as soon as it gets power from
your Raspberry Pi. So, once you have connected it, the display should indicate the
eCO2 level. You will then learn how to interact with the board, receiving readings
and controlling the LEDs and buzzer from a Python program.
Connecting the Air Quality Sensor (Raspberry Pi 400)
It is very important that you do not push the connector in at an angle, or push it too
hard, as you may bend the pins on the GPIO connector. When the pins are lined up
correctly, it should push into place easily.
The connector fits as shown above. Notice that the bottom edge of the board lines
up with the bottom of the Pi 400's case, and the side of the board leaves just
enough room for easy access to the micro SD card.
Once you have connected the board, power up your Raspberry Pi -- both the power
LED (in the MonkMakes logo) and one of the eCO2 LEDs should also light.
