An Ethernet-enabled scale

By mvuilleu, in DIY, Measures and Internet of Things, july 18,2014.

An automated measure of weight comes in useful for many automation applications: not only for getting the weight, but also for detecting the presence of an object or animal, or even for counting items. So we wanted to experiment with it for quite some time already. But we were missing a key piece of the puzzle until very recently, that is, until the arrival of the Yocto-milliVolt-Rx.

Transforming the Yocto-milliVolt-Rx into a USB ammeter

By martinm, in Measures and Electronics, july 04,2014.

Last week, we presented our brand new USB voltmeter, the Yocto-milliVolt-Rx enabling you to measure voltages with an accuracy of the order of a ten of µV. Obviously, some of you asked: "Can we have the same thing with an ammeter?". Good news: it's almost trivial to transform the Yocto-milliVolt-Rx into an ammeter.

Using the new Yocto-milliVolt-Rx for pH measures

By mvuilleu, in Measures and New stuff, june 27,2014.

After the Yocto-Volt and the Yocto-0-10V-Rx, we add today the Yocto-milliVolt-Rx to our family of electrically isolated voltage sensors. This new module is specifically designed for precision measures of low electric signals, from less than a millivolt to a maximum of 2V. Its design enables a direct measure of very fragile voltages, such as in a pH probe for instance.

SRF06: a cheap range finder

We are often asked if we have any plan for a range finder. Well, the answer is "no, not a this time". However, we do have some reasonable alternatives.

Installing the VirtualHub on a QNAP NAS

By Sébastien Rinsoz, in Tiny PC and Measures, may 21,2014.

Until now, it was possible to run the VirtualHub on a QNAP NAS, but only for the NAS servers using an ARM processor. Moreover, we didn't have a .qpkg file to make installation easier. We are putting this straight by providing you with a QNAP package to easily install the VirtualHub from the NAS web interface. This enables you to easily monitor the temperature of the room hosting your NAS using a simple Yocto-Temperature.
