The issue with most screens is that they need to be constantly powered to display information. There is however an exception: the e-paper (or electronic paper) technology. This week, we take advantage of this technology to build a connected screen able to work for months on a single battery charge.

Creating a connected night light

By seb, in DIY and Internet of Things, september 21,2016.

IKEA makes pretty ghost-shaped night lights, but the power cable of these "SPÍKA" is very thin. One children has torn this cable and called Yoctopuce for help. At first, we thought that we would simply fix the power cable but, in the end, we decided to improve this night light by transforming it into a "connected night light" with a Yocto-Color-V2 and a YoctoHub-Wireless-SR.

Monitoring electric consumption over GSM

By mvuilleu, in Measures and Internet of Things, september 09,2016.

A few years ago, we explained why the Yocto-Watt is limited to 16A and we gave you some clues on how to measure high currents. But, at that time, we didn't have a simple solution to offer for the most current application: measuring and transmitting the main consumption parameters of a power distribution panel. This gap is today filled and we offer you a detailed solution, easy to implement, based on commercial components.

Managing the heating of a chalet with a YoctoHub-GSM-2G

By seb, in Internet of Things and DIY, july 21,2016.

A classic example of home automation is to remotely manage the heating system of a second home. In Switzerland, many chalets are equipped with heating systems which are managed by a device connected directly on the phone line. Most of these devices work only on an analog line. If you suppress the phone line or switch it to IP telephony, you must change the device. This week, we are going to see how to replace one of these devices with Yoctopuce modules.
