Video of v1.0

(Click to enlarge)

Overview:

Four touch sensors (capacitive) are used to select various menu items.

Microcontroller is the Adafruit Feather ESP32-S3 with 2MB PSRAM 4MB Flash #5477.

On a 2.8" TFT, the board displays the following:

- Internet time

- Temperature (C), Humidity (%), Barometric Pressure (hPa)

- CO2 (ppm)

- CO (ppm)

- Air Quality (TVOC)

- Light (Lux)

Components:

Vendors: Adafruit Feather ESP32-S3 2MB PSRAM with JC2432S028 2.8" TFT 240x320 ILI9341 Display or 4.0" TFT 320x480 ST7796S TFT Display.

ESP32 Arduino Code for 2.8" display with ILI9341 drivers:  _ESP32-S3_ILI9341-2.8inch_5-Sensors_2f.ino

This board has been tested as v1.0 and updated to v1.1. 

ESP32 Arduino Code for 4.0" display with ST7796S drivers: _ESP32-S3_ST7796S-4.0inch_5-Sensors_2a.zip

The video update time on the 4.0" display is very slow so we won't be doing any further dev with this display.

Testing During Assembly:

Insert only the BME280 sensor and run the Adafruit test file bme280test.ino

If you're using the AHT10 instead, run the Adafruit test file adafruit_aht10_test.ino

Remove the BME280, insert the VEML7700 and run the Adafruit test file veml7700_test.ino

Remove the VEML7700, insert and test the Sensiron SCD40 with Sensiron-SCD4x_exampleUsage.ino

Remove the  Sensiron SCD40, insert and test the SGP40 with sgp40test.ino

Remove the  SGP40, insert and test the MiCS5524 with MiCS-5524.ino

If all tests well, install all the sensors and run the full program listed above this section.
