Use ESP32 microcontroller to read and process data from a BME680 sensor
Uses ESP-IDF v. 4, not Arduino
Includes BME680 driver from https://github.com/BoschSensortec/BME680_driver
You will need a BME680 sensor on a suitable breakout board, and an ESP32 development board. This code is tested on Adafruit HUZZAH32 and Pimoroni BME680 breakout but any other board combination should work as well. Change the I2C pin numbers and device address in the code to match your configuration.
Setup ESP-IDF version 4.1 or later according to the official instructions
Copy or clone this code. Use idf.py -p $PORT flash monitor from the command line, or use Visual Studio Code with the Espressif IDF extension to compile and flash the code and monitor the output.
- use Kconfig file(s) to set things like pin numbers
- use BSEC library to further process the sensor data
- use MQTT (or other protocol) to publish processed data
