Overview

• This project interact the particle with thingspeak.
• Particle electron module will retrieve data from weather shield via I2C bus
• In the front end, Thingspeak will receive the data from weather shield and from OpenWeathermap Database
• User will view the most accurate data averaging from all channel.
• Public Thingspeak channel can be view Here
• front end of project overview(refer to picture)

Working Flowchart

Components

• Particle electron(0.7.0 firmware version)
• Weather Meters(sparkfun)
• SparkFun Weather Shield
• Arduino uno

Wiring

• plug the 2 wire that control the windspeed and rain sensor to the weather shield
• additionaly
  • SDA(arduino) -> SDA(electron-pinD0)
  • SCL(arduino) -> SCL(electron-pinD1)

troubleshooting on wiring process

• refer
  • https://learn.sparkfun.com/tutorials/weather-shield-hookup-guide

Interact with thingspeak

• https://thingspeak.com/
• create an account
• create a channel
• go to channel setting
• create more field(a channel- data get send from your device to thingspeak)

• In my sketch, I use field 4,5,6 for example.
• note: make sure your field number match with field number on thingspeak.
• access to amsl.lab.unl@gmail.com() for more example code .

matlab visualization app

• example of matlab code that graph 2 field with filled area

matlab analysis app

• this app allow you to run a program
• retrieve data using matlab given a period of time
• retrieve data from field.
• example show a matlab program that calculate and display avaerage humidity

TimeControl app

• this app work withmatlab analysis you can schedule thingspeak to run a matlab script
• In the example, I show a matlab script that trigger an API provide by ifttt to send you an email when a value reach certain threshold. You can make it send you a phone message to.

example code

• Arduino node
• Particle node

Data export

• Thingspeak allow you to export your data from fields to diffrence format(JSON,XML,CSV)
• simply click "Public view" or "Private view" then click on "Data Export"

Other feature

interact with firebase(DB)

• Google firebase .
  • store data retrieve from sensor to Google fire Firebase
  • https://github.com/rickkas7/firebase_tutorial
• to retrieve data from firebase with programming language
  • https://firebase.google.com/docs/database/admin/retrieve-data
• firebase lib for python
  • https://github.com/ozgur/python-firebase
