The wiring of all sensors and their pin layout is specified in the following chapter.
- check the Raspberry Pi pinout with
pinout\ - or visit pinout.xyz
Most sensors communicate with the Raspberry Pi directly via the I2C protocol. Some have their own software I2C bus, others share one bus.
gpio pins sda=5 scl=6
- gps (blue=sda, green=scl, white=ground, purple=3.3V)
gpio pins sda=22 scl=23
- co2 (white=sda, yellow=scl, black=ground, red=3.3V)
gpio pins sda=12 scl=13
- magnet (blue=sda, green=scl, yellow=ground, orange=3.3V)
gpio pins sda=8 scl=7
- adc (green=sda, yellow=scl, orange=ground, red=3.3V)
gpio pins sda=16 scl=26
- multiplexer (grey=sda, purple=scl, blue=ground, white=3.3V, yellow=3.3V, green=ground)
- climate (yellow=sda, green=scl, blue=ground, purple=3.3V)
- spectral (brown=sda, black=scl, orange=ground, red=3.3V)
- thermal (purple/white=sda, green/black=scl, blue/grey=ground, yellow/purple=3.3V)
These analog sensors need to be interpreted by an analog digital converter first before passed to the Raspberry Pi.
- methane A0 (white=5V, black=ground, brown=digital_out, red=analog_out)
- uv A1 (brown=3.3V, red=ground, orange=out, yellow=en)
- voltage_ref A2
