Web Of Things

Introduction

The Web of Things is a refinement of the Internet of Things by integrating smart things not only into the Internet (network), but into the Web Architecture (application).

• Introduction to Web of Things

Prerequisites

• Knowledge on Arduino Programming
• Hardware Components
  • NodeMCU
  • Raspberry Pi 3 Model B+
  • DHT Sensor
  • LED
  • Connecting Wires
  • Breadboard

Preparing Gateway

• We will be using Mozilla WebThings Gateway for this demo
• Follow this Demo and setup the Gateway

Installing PlatformIO

• First Install an open source IDE like Atom
• Then to install PlatformIO follow this link
• Once it is setup test the Environment by following this blog

Testing the Code

• Install webthing-arduino with latest version and ArduinoJson with version 5.13.x (Since there are compatible issues) for Web of Things libraries
• Install SimpleDHT for DHT libraries
• There are two projects in this repo
  • WoT_Blink
  • WoT_DHT
• Navigate to src/main.cpp in WoT_Blink and WoT_DHT
• Change the ssid and password to connect the NodeMCU to the same network that the Gateway is connected
• Upload Individual Project and check for the device in the Gateway
• For WoT_Blink Toggle the LED in from the Things Dashboard
• For WoT_DHT Check the Temperature and Humidity values in Things Dashboard

Voila we have just implemented Web of Things 😃
