Using Yoctopuce built-in data logger

By mvuilleu, in Programming, june 25,2013.

Most of our USB sensors include an embedded data logger. It is trivial to activate this data logger. However, after using it for a while, we noticed that the programming interface used to retrieve the data is not very intuitive. We therefore decided to bring some improvements to it to facilitate its use. Here is an outline of what will probably change, to provide you with the opportunity to give us your feedback before the choices are definite.

What happens inside the fridge?

By martinm, in Measures, june 14,2013.

What exactly happens when we open and then close the fridge door? Obviously, the light switches on and off, but how do temperature and power consumption vary? To be frank, this question is not quite innocent. I started a while back to have doubts about how well, or bad, my fridge was working. I have therefore decided to get to the bottom of it. And I made some rather interesting discoveries.

What about the enclosure for the LatchedRelay?

By mvuilleu, in Misc, june 07,2013.

You may have noticed that we don't list any enclosure in the related product section of the Yocto-LatchedRelay. The reason is that, because of the power it supports, this relay is a little bit to high to fit as is in one of our standard enclosures. However, if you are ready to do a little work, there is a relatively simple way to make a Yocto-LatchedRelay fit into an enclosure. Here is how...

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.

Cosm alternatives to record sensor measurements

By mvuilleu, in Reviews and Measures, may 22,2013.

A few days ago, our beloved Cosm Beta service that we used to recommend for real-time graphs from your Yoctopuce sensors, has changed its usage terms. Renamed Xively, the web site is now focusing on revenue-generating services. Unfortunately, some essential features that we have been using, such as the ability to choose the display time range on a graph, have disappeared. It is therefore time to look for alternatives to Cosm...
