What It Is

Room humidity and temperature visualization prototype app using Arduino and DHT22 (temperature and humidity sensor) which send the data to Node.js server via router and socket.io. On the client side the humidity data is visualized using a 2D physics engine called Matter.js so that the particles are interactive and applied 2D physics.

How It Works

Arduino

Circuit

Will come soon...

Code

Configure your WiFi network in arduino_secrets.h.

#define SECRET_SSID "Your Router's SSID"
#define SECRET_PASS "Your Router's Password"

And enter your server address in arduino_nodejs.ino.

char serverAddress[] = "Your server address";

Server

In 'package' directory

$ npm install

And then run the server

$ node index.js

And then you should be able to see the app from http://localhost:8080
