]]> Many IoT projects collect data from a sensor and send the data to ThingSpeak at the same time over and over. To continuously collect and send data to the cloud requires the device to be powered and connected all of the time. A battery-powered IoT device like a Particle Photon or Onion Omega2 would run out of power quickly. There are many IoT applications where you want your IoT device to collect the data offline over a long period of time, then send the data all at once to ThingSpeak for analysis.

The ThingSpeak team at MathWorks is excited to announce Bulk-Update! This new ThingSpeak feature is targeted at IoT devices trying to optimize battery use by allowing the device to update a lot of data at once. To help you get started with bulk-update, we have written examples for Arduino, ESP8266, Particle Photon, and the Raspberry Pi 3.

Once your data is on ThingSpeak, it is easy to analyze using the MATLAB Analysis and Visualization apps within ThingSpeak, MATLAB Online, or Desktop MATLAB. To read data from ThingSpeak into MATLAB, use the ThingSpeak Support Toolbox and the thingSpeakRead command. We have released documentation and examples to help you get started with bulk-update on ThingSpeak.

]]> Allie Fauer, a designer from New York, has released another awesome Instructable tutorial on how to build a “To Do List Reminder Light”. This project is very creative and easy to build on your own. Allie tracks her tasks on an app called Todoist. With a little help of the MATLAB Analysis app on ThingSpeak, Allie is able to analyze her tasks and alert herself of anything overdue. She gently reminds herself with a glowing “Remembrall” globe.

To Do List Reminder Light

Allie uses the MATLAB Analysis app on ThingSpeak to check her to do list and see if anything is overdue. If a task is overdue, the MATLAB code writes the task overdue into a ThingSpeak channel. The MATLAB code is very straightforward and does a bit of analysis on her task list to see what is overdue. To get the MATLAB Analysis code to keep checking her task last, she schedules the MATLAB code using the TimeControl app on ThingSpeak.

Allie also has other ideas on how to make use of her status light:

  • Alert you when you’ve forgotten to water your plants
  • Tell you when you’re out or range of important objects like your keys or wallet
  • Combine with IFTTT to alert you when you’ve forgotten to respond to emails or phone notifications

To build your own Remembrall light, follow the step-by-step tutorial on Instructables.

Particle Electron Kit using ThingSpeak IoT

The Electron is a new 3G connected IoT device using cellular data and works anywhere you can get 3G in the United States. It is really awesome to plug-in a device and get it connected without the issues of Wi-Fi. This development kit also makes it possible to build battery-powered, mobile sensors. Good thing that ThingSpeak supports GPS data and offers sensor data analytics.

Check out Julien’s tutorial to go “From 0 to IoT in 15 Minutes” and other ThingSpeak projects on Hackster.io.

]]> We are thrilled to announce the official ThingSpeak Communication Library for Arduino and Particle devices. This library enables an Arduino or other compatible hardware to write or read data to or from ThingSpeak, an open data platform for the Internet of Things with built-in MATLAB analytics and visualization apps.

Arduino IDE Installation

In the Arduino IDE, choose Sketch/Include Library/Manage Libraries. Click the ThingSpeak Library from the list, and click the Install button.

Particle / Spark IDE Installation

In the Particle/ Spark Web IDE, click the libraries tab, find ThingSpeak, and choose “Include in App”.

Compatible Hardware

  • Arduino or compatible using an Ethernet or Wi-Fi shield (we have tested with Uno and Mega)
  • Arduino Yun running OpenWRT-Yun Release 1.5.3 (November 13th, 2014) or later.
  • Particle Core or Photon (Formally Spark)

ThingSpeak Examples

The library includes several examples to help you get started.

  • CheerLights: Reads the latest CheerLights color on ThingSpeak, and sets an RGB LED.
  • ReadLastTemperature: Reads the latest temperature from the public MathWorks weather station in Natick, MA on ThingSpeak.
  • ReadPrivateChannel: Reads the latest voltage value from a private channel on ThingSpeak.
  • ReadWeatherStation: Reads the latest weather data from the public MathWorks weather station in Natick, MA on ThingSpeak.
  • WriteMultipleVoltages: Reads analog voltages from pins 0-7 and writes them to the 8 fields of a channel on ThingSpeak.
  • WriteVoltage: Reads an analog voltage from pin 0, converts to a voltage, and writes it to a channel on ThingSpeak.

Complete open source code and examples for the ThingSpeak Library are available on GitHub. Discover other MathWorks Open Source and Community Projects on GitHub.
