Think of an IoT project as two parts. One part of the project is where you need to program a thing to send data. And, the second part is where you want to see that data. ThingSpeak sits in the middle and makes it handy to do both, as <a href=\"https:\/\/github.com\/Mjrovai?tab=repositories\">Marcelo Rovai<\/a> points out. Once you have a system like Marcelo&#8217;s set up, you can take advantage of integrated online <a href=\"https:\/\/www.mathworks.com\/company\/newsletters\/articles\/developing-an-iot-analytics-system-with-matlab-machine-learning-and-thingspeak.html\">MATLAB Analytics<\/a>.<\/p>\n<p><a href=\"https:\/\/www.instructables.com\/id\/IoT-Made-Easy-With-UNO-ESP-01-ThingSpeak-and-MIT-A\/\"><img decoding=\"async\" loading=\"lazy\" width=\"620\" height=\"181\" class=\"aligncenter size-full wp-image-2220\" src=\"https:\/\/blogs.mathworks.com\/iot\/files\/2017\/12\/ThingSpeak_in_the_middle.jpg\" alt=\"\" \/><\/a>Marcelo\u00a0has put together a great <a href=\"https:\/\/www.instructables.com\/id\/IoT-Made-Easy-With-UNO-ESP-01-ThingSpeak-and-MIT-A\/\">tutorial<\/a>\u00a0that uses ThingSpeak in the middle to collect data from sensors and then display the sensor readings on a custom Android app running on a mobile phone. He uses the MIT App Inventor to create\u00a0a custom Android app to see the sensor data and status of the\u00a0system. This project uses easily accessible hardware to build a proof-of-concept IoT system to monitor air temperature, humidity, soil\u00a0temperature, soil humidity, and luminosity. Other people could modify this project with different sensors or actuators and build something for their own purposes or build a prototype for your next meeting at work.<\/p>\n<p><a href=\"https:\/\/www.instructables.com\/id\/IoT-Made-Easy-With-UNO-ESP-01-ThingSpeak-and-MIT-A\/\"><img decoding=\"async\" loading=\"lazy\" width=\"620\" height=\"466\" class=\"aligncenter size-full wp-image-2222\" src=\"https:\/\/blogs.mathworks.com\/iot\/files\/2017\/12\/ThingSpeak_App_Inventor.jpg\" alt=\"\" \/><\/a><\/p>\n<p>Check out the full project tutorial on <a href=\"https:\/\/create.arduino.cc\/projecthub\/mjrobot\/iot-made-easy-w-uno-esp-01-thingspeak-mit-app-inventor-da6a50\">Arduino Project Hub<\/a> and <a href=\"https:\/\/www.instructables.com\/id\/IoT-Made-Easy-With-UNO-ESP-01-ThingSpeak-and-MIT-A\/\">Instructables<\/a>.
