Overview

This code is made for an ESP32 Arduino board
The system is able to:

• Collect data from 8 sensors
• Send it to an API (hosed on EPF servers)
• Send it at a custom time interval (minimum every 5 min)
• Automatically synchronize time by calling an external time API
• Restart the connection if it is unable to connect, restart the whole system if it is for a too long time

Secrets variables

Another file must to be added that is not on the repositiry because it constains secrets variables. You have to create a secret_keys.h file and fill it with:

#define EPF_API_KEY "an api key"
#define WIFI_SSID "network name"
#define WIFI_PASSWORD "network password"

Replacing the strings with your values

Files

Other than the secret_keys.h, here are the files provided here:

• app.ino contains the main behaviour of the ESP32
• client.h contains the functions related to WiFi connection
• sensors.h contains the functions related to sensors
