𝗣𝗿𝗼𝗷𝗲𝗰𝘁 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻:
In this tutorial, we will be interfacing SGP30 CO2 & TVOC Sensor with Arduino and display the value on OLED Screen. The SGP30 Sensor is capable of detecting equivalent Carbon dioxide & Total Volatile Organic compounds from the atmosphere. In an earlier project, we measured CO2 & TVOC using CCS811 Gas Sensor & also BME680 integrated environmental sensor.

But SGP30 is a completely different sensor and has the ability to give proper reading quickly. While the CCS811 requires a burn-in of 48 hours and a run-in of 20 minutes the SGP30 is ready to go after just 15 seconds.

In this project, we will first read the CO2 & TVOC value from SGP30 Sensor using the Arduino Sparkfun library & display their value on the Serial Monitor. The sensor can also measure the ethanol and Hydrogen values in raw format. Later we will display the sensor reading on a 0.96″ I2C OLED Display and test the sensor by introducing some perfume near the sensor.
