Infineon - Co2 Buddy

thingiverse

Infineon released a little project called the CO2 Buddy This is the links to the project and the files for reference I've added my modified plate and ring so it fits together better and the light shows through https://www.hackster.io/Infineon_Team/co2-buddy-a904f5 https://hackaday.io/project/186682-co2-buddy?fbclid=IwAR113H4xrVWkVxuhmK0XTvxKy4pZuQh9y8B65dvNY1QxHOOEvk4CdevmVFo https://www.electromaker.io/project/view/co2-buddy Infineon library https://github.com/Infineon/arduino-pas-co2-sensor Neopixel Library https://github.com/adafruit/Adafruit_NeoPixel Source Code https://www.hackster.io/code_files/604971/download Text taken from hackaday Ready - set - print Print the attached CO2 Buddy base (black)Which will hold all the electronic components CO2 Buddy housing (black) CO2 Buddy top (black) CO2 Buddy ring (transparent)Which will assemble to the cover which can be stacked on top of the base Electronics This project is as simple as it can be. Glue the three components on each position given by the "CO2 Buddy base" and connect them according to the schematic below. red - 5V black - GND yellow - I2C SCL green - I2C DATA blue - NEOPIXEL DATA Software The Arduino code below will fade from green (800ppm) over yellow (1400ppm) to red (2000ppm) and send the current CO2 value on a Serial COM port (9600baud) every 5sec.
