ESP32 Arduino: Using an infrared CO2 sensor – EverythingESP

Introduction. In this ESP32 tutorial, we will check how to get measurements from a C02 sensor, using the Arduino core. The sensor used was an Analog Infrared CO2 Sensor from DFRobot. You can find the Wiki page for the sensor here. Note that the code we are going to be developing here is based on the code available on the Wiki page of the product, which I encourage you to check.

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

Jul 25, 2021· 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 ...
