ESP32 CO2 Monitor Tutorial: Interfacing Sensirion SCD30 Sensor (Arduino IDE)

Learn how to build a high-accuracy DIY Air Quality Monitor using the ESP32 and the Sensirion SCD30 sensor. In this tutorial, I will show you how to interface the industrial-grade SCD30 to measure CO2 levels, temperature, and humidity using the Arduino IDE.
We will cover the complete circuit diagram, wiring the I2C pins (SDA/SCL), and installing the required Adafruit libraries to get your sensor data on the Serial Monitor instantly.
