Node-RED is a visual programming language that can be used to connect various Web services, API or peripherals together. Node-RED can use data coming from a Web server, a MQTT broker, a mail server or even Twitter, but not from Yoctopuce sensors. That is, until yesterday...
Last year, Microsoft announced the Azure IoT Suite. Behind this somewhat pompous name hides two examples of use of their Azure cloud with connected objects. We are going to see how to use Yoctopuce modules in one of these two examples.
This week, we present a small and quite simple DIY project based on the fact that white ping-pong balls make excellent light diffusers. We built a kind of multicolor chandelier, that you can drive through the Internet and which is PoE powered.
The Yoctopuce business model is rather simple: Yoctopuce designs, manufactures, and sells electronic modules, provides the libraries necessary to exploit them, as well as support to help customers realize their projects. However, Yoctopuce doesn't provide turn key solutions. Nevertheless, Yoctopuce support regularly receives requests of the type: "How can I display a graph with the values of a Yoctopuce sensor?", or "How can I obtain the values of a Yoctopuce sensor in the CSV format?". So we decided, once will not hurt, to offer you a ready to use application to trace graphs with the values of Yoctopuce sensors.
For a while, researchers have been publishing almost every week new security breaches linked to bad design or configuration errors in the Internet of Things: unprotected security cameras, connected objects serving as Trojan horses, and so on. As we also manufacture network modules enabling you to build connected systems, we must take stock of the situation, so you know what to expect.
