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.
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.
While exchanging with our customers on the best ways to interface industrial controllers, we noticed that nowadays the small secrets enabling you to use an RS485 interface were sometimes unknown from engineers implementing computer or internet based automation. So here is a quick remedial course...
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.
Some time ago, we did an experiment that might interest you. Its goal was to check the behavior of the YoctoHub-GSM-3G-EU when it switches from one provider to another one in roaming. We therefore needed a moving YoctoHub-GSM, so we created an autonomous GPS tracking beacon that communicates by GSM.
