Remote monitoring with the Valarm cloud

By mvuilleu, in Measures, Reviews and Internet of Things, july 31,2015.

There are more and more services enabling you to store your measures in the cloud. We already presented free (but limited) solutions such as EmonCMS and ThinkSpeak, and more recently the commercial solution Microsoft Azure. Today, we present the professional solution developed by our US reseller, Valarm.net, which is today the only one to exploit the advanced features of Yoctopuce modules and also offers features linked to geolocation that you don't find in other services.

Viewing temperature flows

By mvuilleu, in Reviews and Measures, june 07,2015.

Summer is coming and, with it, heat waves that put a strain on the air conditioning of server rooms. How can we know if an air conditioner is of the right size or if it labors to cool the room and risks to fail at any time? How can we know if fresh air is distributed everywhere, or if the addition of a simple air circulator could save a few KWh?

The Intel Edison and Yoctopuce

By martinm, in Reviews, february 27,2015.

We briefly tested the Intel Galileo board a few weeks ago. This made us want to test the latest from Intel, that is the Edison. This thing is literally a Linux x86 PC, with the size of a stamp. We really wanted to know if it was possible to use it to drive Yoctopuce modules. Indeed, its size makes it particularly interesting for any embedded system. So we bought one and we played with it...

Light sensors comparison

By mvuilleu, in Reviews, New stuff and Measures, january 23,2015.

Some time ago, we had to stop making the Yocto-Light because the OSRAM light sensor that we used on this module stopped being produced. As a replacement, we now offer two products: the Yocto-Light-V2, more reactive, based on an AVAGO sensor, and the Yocto-Light-V3, truer to the human eye, based on a ROHM sensor. Let's see how they compare...

First tests of the LIDAR-Lite telemeter

By mvuilleu, in DIY, Measures and Reviews, january 09,2015.

When you wanted to measure a distance at a precise location, there wasn't, up to now, any middle range between very expensive laser telemeters (of the Baumer type) and cheap sensors (of the Sharp type). These cheap sensors don't provide a real measured value and are very limited distance-wise. Therefore, we were particularly interested in the LIDAR-Lite project which announced a distance measure of several meters for under $100. Nine months later, the baby is here at last and we can test the final version of the product to try out this new technology.
