By seb december 18,2021.

This week, we are going to talk about programming. Support has recently received an interesting question: "how can you register an object method as an arrival callback".

Using Electron in TypeScript, the way we like it

People like the TypeScript language as much to create web interfaces as to write Node.js software which work as a service, with complete access to the machine resources. You can also write traditional applications in TypeScript, that is applications which combine a graphical interface and access to all the resources of the machine, for example to access a database or files. We are going to explore this scenario and see how to access Yoctopuce modules in such a scenario.

GSM power usage for sensor monitoring

By mvuilleu, in Measures, Electronics and Internet of Things, november 20,2021.

When you must design a system that sends back measures through a GSM connection, there are two physical quantities that you want to estimate: que quantity of transferred data and the power consumption. We already had the opportunity to provide orders of magnitude for data consumption in a previous post, but we are going to see today how much power is needed to send back data periodically through a 3G or 4G GSM connection.
