Arduino | Adafruit SCD-30 - NDIR CO2 Temperature and ...

· The sensor has a lot going on, there's temperature and humidity reading thanks to an SHT31 sensor on board. These values are used internally to normalize the NDIR CO2 readings as well. You can only get data every 2 seconds, which is pretty fast for this kind of sensor! If you want to slow down the readings to reduce power usage, uncomment this section:

Arduino | Adafruit SCD-30 - NDIR CO2 Temperature and ...

· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

· If a "good" message appears, then connection is well made and the sensor heating process ("heat") will continue, which lasts 30 seconds for the Sensirion and Cubic sensors, and 3 minutes for the Winsen sensors. If the message is "fail" then the connection failed and we must verify the connection between the Arduino and the sensor. After heating up, the CO2 value in parts per million ppm appears on the screen. When the value is higher than the Beep level, the alarm …

Tindie Blog | A CO2 Sensor for ESPHome

· The MH-Z19B is a pretty neat sensor. It uses non-dispersive infrared to detect the concentration of CO2 in the air. This makes it pretty immune to the percentage of oxygen in the air, and with no moving parts or chemical sensor elements it should have a fairly long lifespan. It can detect concentrations up to 5000 ppm, at which point most ...
