Indoor air quality sensor box IoT project with 3D-printed housing!
Measures the CO2 level in the room and gives a warning when to ventilate. All values are also distributed via MQTT.
CO2 Meter exporter to use with Prometheus, optimised for Raspberry Pi.
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 ;-)
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
