Make a a traffic light that tells you when to ventilate a room
MICS4514 Breakout board sensor for CO2 and NO2 only 3.3v
DIY CO2 sensor with traffic light and display for air quality indication
This sketch uses three independent sensors to measure the indoor climate and air quality with a high level of precision. The data will be sent to iobroker for further processing and visualization.
LED glows when the CO2 and TVOC levels in the room are too high.
A library to interface esp chips with the SCD4x CO2 sensors in the Arduino (c++) Framework.
🕯🧯💨 A device for displaying CO2 in air (ppm), as well as an alarm when a certain level is exceeded.
Calibration Tool for the SCD-30 CO₂ sensors with the I2C interface such as those sold by Adafruit. Intended for use when calibrating multiple sensors for the DIY Frugal Arduino CO2 Sensor https://github.com/ericwooshem/DIY-Frugal-Arduino-CO2-Sensor
