New product: the Yocto-Altimeter

By mvuilleu, in New stuff and Android, may 11,2014.

The Yoctopuce module family welcomes a new member: the Yocto-Altimeter. As you'll have guessed, it's a barometric altimeter allowing you to determine the altitude (or the relative height) of its location. Some of you already used the barometer of the Yocto-Meteo as an altimeter, but this new module provides much better measures.

How to use Yoctopuce modules in the middle of nowhere

By Sébastien Rinsoz, in Measures and Android, march 27,2014.

How to measure environmental factors (temperature, light, humidity, ...) in a field located kilometers away from any electric socket and any Wifi network? The first solution coming to mind is to use an Android phone and to connect Yoctopuce sensors by USB. This solution works (as illustrated here), but to power this type of installation, you need to use a solar panel and a battery of a relatively large size. To perform some measures for a relatively short period of time (a few weeks), there is a simpler and probably cheaper alternative: using a Wifi connection between the phone and the sensor instead of a USB one.

New data logger and graphs under Android

By Sébastien Rinsoz, in Programming, Measures and Android, february 17,2014.

Last week, we used the new version of the library to trace a dynamic graph in C# .NET. At that time, we saw that the new Datalogger API and the TimedReport made the work a lot easier. This week, we are going to develop a small Android application that also traces a graph from the datalogger and from current values. But we are going to see that things are a little more complex under Android ...

Switching a relay via an SMS

By Sébastien Rinsoz, in Programming and Android, september 24,2013.

We have been recently asked whether we had a solution to communicate with our modules using SMS. We have a long term plan for a GSM version of our YoctoHub, but for now we focus on the YoctoHub-Wifi and other new modules. However, using an Android phone and with some programming, it is quite possible to communicate with a Yoctopuce module via SMS. A classic use is to remotely turn on and off the heating of your vacation home.

Turn on the light from a Pebble smart watch

By Sébastien Rinsoz, in Internet of Things and Android, june 03,2013.

You have most probably already read about the Pebble smart watch, which connects to your phone to let you know about new emails, text messages, incoming calls, etc. A year after the original announcement, Pebble has eventually published the SDK to create an active “Watch App” for this watch. We thought it would be fun and convenient to be able to control our environment directly from a watch. So, to test this new SDK, we have written a small Pebble application that controls the light bulb that we used a couple of weeks ago with the Yocto-LatchedRelay.
