Monitor action of a heating burner by reacting on the sound of the running burner
https://www.hackster.io/RoSchmi/heating-burner-monitoring-using-esp32-and-microphone-80015d
This App for Esp32 monitors the activity of the burner of an oil-heating (or any other noisy thing) by measuring the sound of e.g. the heating burner using an Adafruit I2S microphone The on/off states are transferred to the Cloud (Azure Storage Tables) via WLAN and can be visulized graphically through the iPhone- or Android-App Charts4Azure https://azureiotcharts.home.blog/
The WiFi Credentials, Azure table-name and -key and the sound threshold can be entered via a Portal page which is provided for one minute by the Esp32 after powering up the device. On the first connection to the Portal page a password is needed. This is "My" + the SSID-Name of your ESP32 e.g. MyESP32_xxxxxx
After having entered the credentials one time they stay permanently on the Esp32 and need not to be entered every time.
This App uses an adaption of the 'Async_ConfigOnStartup.ino' and 'Async_ConfigOnSwitchFS'as WiFi Mangager from: -https://github.com/khoih-prog/ESPAsync_WiFiManager

For Adafruit Huzzah Esp32:
static const i2s_pin_config_t pin_config_Adafruit_Huzzah_Esp32 = { .bck_io_num = 14, // BCKL .ws_io_num = 15, // LRCL .data_out_num = I2S_PIN_NO_CHANGE, // not used (only for speakers) .data_in_num = 32 // DOUT };
// For Esp32-Dev_KitV V4:
static const i2s_pin_config_t pin_config_Esp32_dev = { .bck_io_num = 26, // BCKL .ws_io_num = 25, // LRCL .data_out_num = I2S_PIN_NO_CHANGE, // not used (only for speakers) .data_in_num = 22 // DOUT };
