Industrial Internet of Things Demo

This demo is to demonstrate the real-time percentage of substances in a spherical or cylindrical container which would be transmitted to the server, and trigger SMS with info from Twilio, and other external data sources directly from the hardware layer.

Build Instructions

• From the Arduino IDE 1.8.9, navigate to Sktech > Include Library > Manage Libraries
• Filter using Firebase Arduino Client Library
• Install the one by Mobizt, version 2.7.0
• On the codebase, update network credentials & RTDB credentials:
  • Change the WIFI_SSID with yours
  • Change the WIFI_PASSWORD with yours
  • Change the API_KEY with yours
  • Change the DATABASE_URL with yours
• Update sendDataIntervalMillis, currently it's set as 10000 which means it sends/stores data to RTDB every 10 seconds
• The codebase on setup():
  • connects the WiFi on the ESP32 to the WiFi Router/Hotspot
  • signs up using FirebaseAuth and FirebaseConfig
  • assigns the callback function for the long-running token generation task
• The code on loop():
  • generates random values as ints & floats
  • sends/stores those int & float to the database path Test/random_Float_Val
• Ensure your setup/IDE has selected the correct ones, i.e. ESP32 Dev Module as Board
