Remote device control using WebSocket callbacks

By mvuilleu, in New stuff and Programming, december 26,2015.

websocket_iconUntil now, there were two different ways of accessing Yoctopuce devices over the network: either by direct connection over a local network, or using the special HTTP callback mode which makes it possible to drive a Yoctopuce module sitting on a remote network behind a NAT filter. The HTTP callback method however had some limitations. Today, we are introducing a new connection method, named WebSocket callback, that brings all direct connection features to the callback scheme.

Experimenting with EcmaScript 2015

By mvuilleu, in Programming and New stuff, december 18,2015.

JavaScript comes back from far away. Originally, it was only a source of incompatibilities and a nightmare for web designers. Having to code a version for IE and one for Netscape on the same web site was commonplace. Fortunately, the JavaScript language has evolved amazingly to become the ubiquitous companion of HTML5 on almost all internet sites on the planet. With the latest version of the language, adopted as a new standard this past Summer, new possibilities came into being. They deserve to be known and exploited.

New product: the Yocto-4-20mA-Tx

By martinm, in New stuff, december 11,2015.

This week, we present the alter-ego of the Yocto-4-20mA-Rx, that is the Yocto-4-20mA-Tx. This small module enables you to control industrial actuators, as long as they have a 4-20mA input. Let's have a closer look, shall we?

Using Yoctopuce sensors with InfluxDB and Grafana

By mvuilleu, in Reviews and Measures, december 05,2015.

Yoctopuce sensors are sold with programming libraries rather than with turnkey software for a specific use. Therefore, most of Yoctopuce users are developers. We do provide a few ready-to-use tools such as the command line interface, somewhat rustic, or the integration into third party solutions such as EmonCMS or Valarm. Today, we present a new solution of this type: an integration with InfluxDB and Grafana.

Running a system on batteries

By martinm, in Electronics, november 27,2015.

As long as your expectations are in line with the laws of physics, it is not a problem to build a battery-powered system with Yoctopuce devices. We have already covered this topic a few times on this blog, but this week we will provide some theory and see how we can compute the life time of a system based on the battery size, how to build a self-powered system, what are the pitfalls to avoid...
