By thibaut, in DIY and Internet of Things, december 07,2018.

We already discussed home-made weather stations in our blog, but none before had this "pagoda" design or used this messaging protocol. That's why we are writing a new post. The aim of this "low cost" weather station is to build it with materials as basic as possible

Adding series to Yocto-Visualization

By martinm, in Programming and Electronics, november 30,2018.

Customers have asked us several times why Yocto-Visualization offers only 4 data series per graph and whether it is possible to have more. The explanation is simple: we had to choose a limit, and a maximum of 4 seemed reasonable. Nevertheless, it's rather easy to modify the application to have more series, and this week we show you how to do so.

Electric consumption has been at the heart of the news in recent years. Being great fans of graphs and measurements, we propose a small system allowing you to follow in real time the electric consumption of a workbench. As I am new here at Yoctopuce, I was appointed guinea pig to do it my own way, while discovering Yoctopuce modules at the same time.

How to handle a serial protocol automatically

By mvuilleu, in Misc, november 09,2018.

Yoctopuce serial communication modules are more than simple interfaces: they are able to query and analyze autonomously the data coming from any device to then present the results in the way of a Yoctopuce sensor and/or record them in the embedded data logger. But in order to do so, you must tell the Yoctopuce module how to manage the dialog with the device. So here are a few examples as a complement to the documentation, to make this task easier.
