Automating a coffee machine with a Yocto-Proximity

By seb, in DIY and Internet of Things, january 27,2017.

Five years ago, we modified our Jura coffee machine, which we nicknamed Josephine, to control it remotely via a web page. The idea was amusing but in fact this feature wasn't really useful as we still had to get up to place a cup in front of the coffee machine. But today, thanks to the Yocto-Proximity, we can do something more useful: We are going to brew a coffee as soon as a cup in placed on the machine.

New! The Yocto-Proximity

By martinm, in New stuff, january 20,2017.

This week, we present the latest addition to the Yoctopuce range, the Yocto-Proximity. It's an infrared proximity sensor which allows you to detect the presence of objects without physical contact. Let's see what it's all about...

Optimizing the reading of Yoctopuce sensors

By mvuilleu, in Programming, january 13,2017.

The Yoctopuce API has several distinct mechanisms to optimize access to the sensors, through USB as well as through the network. In a previous post, we talked about the polling and callback methods and compared their respective advantages. Today, we offer a new intermediary method, enabling you to optimize access to some sensor attributes, when you can't do it with a callback.

Using Yoctopuce sensors with Node-RED

By seb, in Internet of Things and Programming, january 06,2017.

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...

The Yocto-Thermocouple and ground loops

By martinm, in Measures, december 30,2016.

From time to time, a customer contacts Yoctopuce support to complain about significant instabilities on measures performed with a Yocto-Thermocouple. Each time, the conclusion is the same: the instabilities are the result of an unwanted ground loop. The Yocto-Thermocouple is not an electrically isolated module: there is no electric separation between the measuring part and the USB part. This has consequences that you must clearly understand. This is what we are going to explain this week.
