Storing real-time measurements in a CSV file

By mvuilleu, in Measures and Programming, september 30,2022.

Although Yoctopuce sensors have a built-in data logger, it is often useful to store the data in a database or CSV file for local processing. Ideally, one would like to fetch the data in real time as much as possible, but reserving the possibility to retrieve the data stored by the module in case of temporary connection loss. And this is not so difficult to do...

Who did fail to properly close the fridge (again)?

At Yoctopuce we have a small refrigerator that is used to keep the stock of solder paste, a few bottles of water and occasional picnics cool. We've noticed that the little flick of the wrist we all usually give the door isn't always enough to close it. It then stays open for hours before anyone notices.

Display your Todoist tasks on a Yocto-MaxiDisplay

A few years ago, we embedded a Yocto-MaxiDisplay in a kitchen. This device displayed upcoming events by connecting itself to a Google agenda. 8 years later, the system still works, but instead of displaying a calendar, we would like it to display the items of a Todoist to-do list.

Labelling component boxes

With the current supply difficulties, it is crucial to have a rigorous inventory management. We already showed you two tools based on Yoctopuce modules that we implemented, which take advantage of the DataMatrix 2D code labels found on most electronic component reels. Today, we are going to see how to manage items which do not have such a label.

Managing power outages

Here in Switzerland, there is a risk of energy shortages during next Winter, and we can't exclude having scheduled or unscheduled power outages. We took this opportunity to build a small device to help up manage the consequences of potential power outages.
