Logging and retrieving measures without network access

By mvuilleu, in Tiny PC and Measures, december 02,2016.

Even in the Internet of Things era, there are automation and measuring applications that require to work in a completely autonomous way, without any network connection of any kind. Someone asked us recently how to implement such an autonomous data logger using our sensors. The system should not require any network connection but use a USB key to retrieve the data. We are going to cover this example in details and at the same time take this opportunity to test a relatively new mini-computer that we recently discovered...

Our new Android app: Yocto-Toolbox

By seb, in Android and New stuff, november 27,2016.

We often receive requests for an Android version of the VirtualHub. It doesn't exist, but we provide an Android library enabling developers to use our modules directly from their app. However, we didn't have a solution for users who don't want to develop their own applications. We adjust our aim by announcing our new Android application: Yocto-Toolbox.

A Yoctopuce web based app to draw sensors graphs

By martinm, in Internet of Things, november 18,2016.

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.

IoT: Should you be afraid of Yoctopuce devices ?

By mvuilleu, in Internet of Things, november 11,2016.

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.

Controlling Yoctopuce modules from MQTT

By seb, in Programming, november 05,2016.

YoctoHubs can automatically publish sensor values on a MQTT broker, as we illustrated in a previous post on this topic. However, for scalability and security reasons, YoctoHubs cannot use MQTT messages to drive connected modules. There are however circumstances where it might be desirable to integrade Yoctopuce command devices in an existing MQTT architecture. In this case, it is enough to use a small gateway between the MQTT protocol and the Yoctopuce modules. This is what we are going to do this week.
