What is ThingSpeak?

ThingSpeak is IoT Cloud platform where you can send sensor data to the cloud. You can also analyze and visualize your data with MATLAB or other software, including making your own applications.

The ThingSpeak service is operated by MathWorks. In order to sign up for ThingSpeak, you must create a new MathWorks Account or log in to your existing MathWorks Account.

ThingSpeak is free for small non-commercial projects.

ThingSpeak includes a Web Service (REST API) that lets you collect and store sensor data in the cloud and develop Internet of Things applications. It works with Arduino, Raspberry Pi and MATLAB (premade libraries and APIs exists) But it should work with all kind of Programming Languages, since it uses a REST API and HTTP.

IoT Sensors

DHT11/DHT22 Temperature and Humidity Sensor

The DHTXX sensors are temperature and humidity sensors and they comes in 2 flavours: DHT11 and DHT22. They contains a chip inside that does some analog to digital conversion and spits out a digital signal with the temperature and humidity. Read more.

Want to make your own Cloud Service?

ThingSpeak has many limitations and it costs money if you want to use it for real and professional applications.

So why not create your own Cloud Service from scratch? See Cloud-based Datalogging and Monitoring Examples.
