Monitor Indoor Air Quality with SGP40 Sensor & ESP32-S3: Real-Time VOC Index on TFT Display!

Keeping track of your indoor air quality is essential for a healthier and safer home environment. In this video, we'll show you how to use the SGP40 air quality sensor, interfacing it over I2C with the powerful ESP32-S3 microcontroller. Our setup features a vibrant 2.8-inch TFT display driven over a parallel interface, making it easy to visualize your air quality data.

We harness the dual-core power of the ESP32-S3 to process sensor data using Sensirion's algorithm, converting it into a VOC (Volatile Organic Compound) index—a key measure of air quality. With FreeRTOS running on separate cores, we ensure smooth operation and seamless updates to the LCD.

To top it off, we'll display the VOC index on a beautifully crafted user interface designed with LVGL and Squareline Studio. Ready to learn more about the air you breathe? Let’s dive in and put the show on the road!

Just wanted to know which display library is used to have such a fancy display

[jacekf]

does it have to be S3? how about just ESP32? ESP8266?
