Instructions

Once it's all connected, it should look like this:
Check your wiring carefully and then power up your Raspberry Pi -- both the power
LED (in the MonkMakes logo) and one of the LEDs should also light.
Unplugging the Air Quality Board
Before removing the board from a Raspberry Pi 400.
1. Shutdown the Raspberry Pi.
2. Gently ease the board off the back of the Pi 400, edging it a little from each side
in turn, so as not to bend the pins.
If you have a Pi 2/3/4 just remove the jumper wires from the Raspberry Pi.
