WiFi Weather Station Description

App & Device can be used to monitor weather conditions in agricultural, industrial or commercial applications and can be expanded to monitor numerous other types of data according to the need of the client, market and by sensors available.

Project is to measure the temperature and humidity in real time with sensors and then transmit the data via WiFi to Firebase, a real-time cloud database, and then display the data with various web technologies in a website interface.

Features to have:

• Use Firebase (a Backend-as-a-Service cloud storage), to store data on its real-time database to log data of temperature & humidity via WiFi
• Viewable results by a website interface
• Real time temperature and humidity monitoring as polled from sensor
• Battery powered, portable device
• Battery voltage divider, for monitoring battery voltage level - 9/12/2017

---

Features to create if time or for future uses:

• Data logging of additional sensors (to display for the use in a variety of industries such as Agricultural, industrial or commercial Applications)
• Weather forecasting provided by 3rd party source by API
• Device location via GPS
• Solar powered battery source to extend battery life

WiFi Weather Station Breadboard Layout

Schematic of layout

Code used for programming the Adafruit Feather HUZZAH ESP8266 board is located in the directory feather_huzzah_esp8266_code.

• Definition of Code
  • weatherStationESP8266.ino - Used to test hardware was setup correctly, sends data to serial monitor.
  • weatherStationESP8266-ep.ino - Used to send data via WiFi to ThingSpeak to verify that data was sending out to a database and receiving data in
  • wsESP8266-DHT11-Firebase.ino - Completed code used to send data via WiFi to Firebase database, updated 9/27/17 ​

I will not be covering how to or about the code portion of the Adafruit Feather HUZZAH ESP8266 board in this description but may at some point include a separate write up on how to do that.

Technologies used for website

Description of technologies used to develop this app.

• REACT Router 4.1.1

• REACT.JS based using create-react-app, currently it is a thin layer on top of many amazing community projects, such as:

• webpack with webpack-dev-server, html-webpack-plugin and style-loader Babel with ES6 and extensions used by Facebook (JSX, object spread, class properties)

• Autoprefixer

• Jest

• ESLint

• All of them are transitive dependencies of the provided npm package.

Dependecies

firebase: 4.1.3,
react: 15.6.1,
react-dom: 15.6.1,
react-router: 4.1.1,
react-router-dom: 4.1.1
