Setup

  1. Install this repository on your machine by downloading the zip file or running this command:
git clone https://github.com/KaranJagtiani/IoT-Application-using-MEAN-Stack.git
  1. Run this command in "node-app" directory, as well as in the "angular-src" directory for installing the necessary node modules:
npm install
  1. Add your broker service credentials in "app.js" and "nodemcu_sketch" files.
    Few free MQTT broker services - Shiftr, Hive MQ, Mosquitto.

  2. Make sure you have an active internet connection, and add your WiFi credentials in "nodemcu_sketch" file.

  3. Upload "nodemcu_sketch" to your Node MCU.

  4. Make sure MongoDB is running:

mongod

Usage

  1. Run the Node server, by running this command in the node-app folder:
node app.js
  1. To use the application, type this in your browser's URL field
http://localhost:3000/
