Raspberry-Pi I2C driver for Sensirion's SCD30 sensor
Python module for reading CO2 concentration from a Senseair S8 sensor connected to a Raspberry Pi
Measures the CO2 level in the room and gives a warning when to ventilate. All values are also distributed via MQTT.
Sensirion I2C driver for embedded platforms for sensor SCD30
Kiwi monitor is an open source CO2/Humidity/Temperature sensor intended for monitoring the quality of the air in a room. Kiwi was created to support teachers with a notification to ventilate their classroom.
The CO2-Ampel detects the CO2 level in the surrounding air.
DIY, low cost esp-platform based CO2 monitor ;-)
CO2 Meter exporter to use with Prometheus, optimised for Raspberry Pi.
C++ library for Infineon's Photoacoustic Spectroscopy (PAS) XENSIV™ CO2 miniaturized sensor
Circuit that recognizes the amount of CO2 in a room. Built with the ESP8266 µC and a MHZ-19B sensor.
MicroPython driver for Sensirion SCD40 and SCD41. Derived from the Adafruit CircuitPython version
This is a project for measuring CO2 concentration as well as humidity and temperature. Different GUI modes are available.
