The local unit will also receive data from the internet, "reading" them from specific ThingSpeak Actuator Channels. The local unit (UNO/ESP-01) will capture data from sensors and actuator status, send them to the Internet, "writing" on a specific Status Channel. So let us learn all about GSM Module with Thingspeak & STM32. ThingSpeak server is an open data platform and API for the Internet of Things that enables you to collect, store, analyze, visualize, and act on data from sensors. The humidity & temperature data will be sent to Thingspeak server using AT Commands for GSM Module.
In this case, results is used to request five results.
Append the second parameter after an ampersand &. Append the first parameter after a question mark ?. To read data from a private channel, supply the Read API Key with the parameter api_key.

To send data faster to ThingSpeak or to send more data from more devices, consider the paid license options for commercial, academic, home and student usage.

To get full access to the MATLAB analysis features on ThingSeak, log in to ThingSpeak using the email address associated with your university or organization. To use ThingSpeak API, you need an API key.
As an example, we’ll publish random values, but in a real application you would use real sensor readings. In this tutorial, you’ll use the ThingSpeak API to publish and visualize data in charts from anywhere.

ThingSpeak has a free API that allows you to store and retrieve data using HTTP. To get the APIID: Open a browser and go to Press the Sign up button and create a free account. Read 10 Results in JSON Format Channel 9 contains information from several home environment sensors. To see the format for an HTTP response, click the link or copy it to your browser. You can use your web browser to complete GET HTTP requests to the RESTful API for ThingSpeak™. You can send data to ThingSpeak from your devices, create instant visualization of live data, and send alerts. ThingSpeak is an IoT analytics platform service that allows you to aggregate, visualize, and analyze live data streams in the cloud. ThingSpeak is the open IoT platform with MATLAB analytics. Sign In to ThingSpeak™ using your MathWorks ® Account, or create a new MathWorks account. Create a channel titled "My Channel" with three named fields: "Stuff", "Things", and "Data".

This example shows how to create a new channel using POSTMAN. Use POSTMAN to Create a New Public Channel You can use POSTMAN to try out your HTTP requests using the RESTful API for ThingSpeak. Commercial users are eligible for a time-limited free evaluation. Free accounts offer limits on certain functionality. Non-commercial users may use ThingSpeak for free. To use ThingSpeak, you must sign in with your existing MathWorks account or create a new one. This example will demonstrate how to publish data to a ThingSpeak channel using the Paho library. It has been adapted to many languages, including Python. Paho is an open source MQTT client library that will be used for this examples. On the Raspberry Pi, an MQTT client library is required to send data to ThingSpeak. On a headless setup, the command line of the Raspberry Pi can be accessed remotely from another computer or device on the same network using SSH (Secure Shell). When the Raspberry Pi boots up, it will detect the SSH file and enable access. This will be useful if you are running the Pi for long time for some application at some remote place and need monitor its CPU temperature. Here Raspberry Pi will read its CPU temperature and send it to ThingSpeak, and it can be monitored from anywhere in the world using internet. Functions are available in just about any programming language and with a little bit of knowledge, data transfer should be fast. In order to be able to use the service, it is possible to simply send the data via “POST” or retrieve via “GET”. If you have an internet-accessible device set it up as a HTTP server and set up a thingspeak react to push the data out to your device.

Wrap the above code in a loop that continually re-reads the data after a delay (at least 15 seconds, possibly more depending on your data).
If you wish to read data continuously you have 2 options. How to read data from thingspeak using raspberry pi
