Getting Started

ThingSpeak Basics

ThingSpeak is an application platform for the Internet of Things. Using ThingSpeak you can build an application around data collected by sensors.

Features of ThingSpeak include:

  • Time series data collection
  • Data analytics using MATLAB®
  • MATLAB visualizations
  • Apps
  • Plugins

Use the ThingSpeak channel to send and store data.

Each channel has:

  • Eight fields that can hold any type of data.
  • Three location fields.
  • One status field.

After you create a ThingSpeak channel you can publish data to the channel, have ThingSpeak process the data, and then have your application retrieve the data.

Here is a live demo of a light sensor publishing data to ThingSpeak:

Internet of Things

The Internet of Things enables you to collect, analyze, and act on data from things. Things are either sensors or actuators. Sensors are devices that inform us about our environment. Think of a temperature sensor, or even the GPS receiver on your mobile phone. Actuators are something that you want to control, things like thermostats, lights, pumps, and outlets. The Internet of Things brings everything together and allows us to interact with our things. For example, you could have your thermostat control itself based on where you are located.

Using ThingSpeak you can:

ThingSpeak Tutorial

The ThingSpeak and MATLAB Tutorial shows how to collect data from a source, analyze the data in MATLAB, and act on the data based on the results of the analysis.

ThingSpeak API

The ThingSpeak API is available on GitHub and includes the complete ThingSpeak API for processing HTTP requests, storing numeric and alphanumeric data, numeric data processing, location tracking, and status updates. The open source version follows the same documentation as the ThingSpeak hosted service.


Please post your questions, comments, and feature requests in the ThingSpeak Forum.

HTTP Headers

If you would like to reduce the number of HTTP headers sent by our application, please add the parameter headers=false to any HTTP request.

API keys can optionally be sent via HTTP headers by setting the header name to THINGSPEAKAPIKEY and the header value to the API key.

Time Zones Reference

Time zones can be specified for any request by adding the timezone parameter with a value corresponding to any identifier found below. Identifier names are case-sensitive, and should be URL-encoded in HTTP GET requests, for example:


The most common time zone identifiers are listed below. ThingSpeak supports all IANA Time Zone Database identifers; a human-readable list is also available.
