Beginning in Node.js with Yoctopuce modules

By mvuilleu, in For the beginners, may 19,2017.

This week, we are going to show you how to make your first steps with Yoctopuce modules in JavaScript, in particular in the context of a web server written with node.js. This scenario is particularly interesting because it allows you to create server applications collecting data from many Yoctopuce sensors scattered everywhere, each sensor transmitting its own data independently over Internet over Wifi, GSM, etc.

Automating YoctoHub configuration

By seb, in Programming, may 12,2017.

YoctoHubs allow you to make available any Yoctopuce module from an Ethernet or Wifi network. This enables you, for example, to use several temperature sensors in distinct buildings. However, before you can access a YoctoHub through the network, you must first configure its network parameters. You can use the VirtualHub or our command line tools, but this week, we are going to see how to automate this step using our libraries.

Yocto-Visualization, a free visualization app

By martinm, in Measures and New stuff, may 05,2017.

We have a present for you today. It's something that people have been regularly asking for, despite our best efforts to be as clear as possible that Yoctopuce doesn't provide ready-to-use solutions. In the end, we decided to make a small exception:-) and to give you an application to easily visualize the values measured by Yoctopuce sensors. If you work under Windows, you will be able to display graphs, indicators, and other gadgets in a few clicks. Follow the guide...

A connected smoke detector

By mvuilleu, in Measures and DIY, april 28,2017.

The usual method to detect smoke consists in measuring the reflection of a light beam on the smoke particles suspended in the air. Although we don't explicitly have a smoke detector in our product catalogue, we recently started offering a product which can be used for this: the Yocto-RangeFinder. Indeed, this sensor uses exactly the same principle for its main feature (distance measurement) and can therefore easily be used as USB smoke detector, or even as a networked smoke detector.

Performance improvement of our API

By seb, in New stuff and Programming, april 21,2017.

This week, we are going to talk again about our programming libraries, to announce a good news: We added an optimization which reduces running time by about 40% and splits by half the quantity of transferred data.
