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.
A noticeable characteristic of Yoctopuce modules is that you can drive them from a server thanks to the HTTP callback API allowing you to work around NAT filters. Obviously, this is truly interesting only if you have a PHP, Java, or ecmascript server. Well, this week we tested some free PHP hosts and we show you in details how to configure them...
The issue with most screens is that they need to be constantly powered to display information. There is however an exception: the e-paper (or electronic paper) technology. This week, we take advantage of this technology to build a connected screen able to work for months on a single battery charge.
IKEA makes pretty ghost-shaped night lights, but the power cable of these "SPÍKA" is very thin. One children has torn this cable and called Yoctopuce for help. At first, we thought that we would simply fix the power cable but, in the end, we decided to improve this night light by transforming it into a "connected night light" with a Yocto-Color-V2 and a YoctoHub-Wireless-SR.
