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/

Have fun!
