ESP32 env monitor

ESP32 based environment temperature and humidity monitor. The repo composes of:

• sensing: the code of the ESP32, which is using two LEDs for status output;
• provider: a simple golang server to expose the socket to the ESP and the rest api to query from webapps;
• web: the main webapp for data visualization

ESP32 LEDs status (which I tend to forget)

Board status

• INITIALIZING: setting GPIOs initial values, preparing WiFI board
• CONNECTING: wifi is connecting to the network
• ACTIVE: connection to the network is ok, DHT is OK, active reading and uploading
• ERROR: DHT init failed or wifi connection failed, required reboot

LEDs status configurations

• INITIALIZING: both LEDs blink for 100 ms every second
• CONNECTING: green OFF, red ON for 100 ms every second
• ACTIVE: red OFF, green ON for 50 ms every two seconds
• ERROR: green OFF, red ON in 500 ms cycles

Open to critics.
