New data logger and graphs under Android

By Sébastien Rinsoz, in Programming, Measures and Android, february 17,2014.

Last week, we used the new version of the library to trace a dynamic graph in C# .NET. At that time, we saw that the new Datalogger API and the TimedReport made the work a lot easier. This week, we are going to develop a small Android application that also traces a graph from the datalogger and from current values. But we are going to see that things are a little more complex under Android ...

Gas sensors

How clean is the air you are breathing? What does it contain, exactly? It's not easy to obtain a full answer with a simple sensor, as one should, in fact, look for all the volatile compounds, one after the other, that could be present. There are however single gas sensors that provide, for specific applications, appropriate answers. Let's see how to use them with the Yoctopuce modules.

GSM temperature monitoring

By mvuilleu, in Measures, december 06,2013.

This week, our mission is to check, through temperature monitoring, that the heating system of a church is working as it should. We are going to show you how to set up the remote monitoring of the surrounding air temperature and of the heater temperature, without needing to write a single line of code. The specificity of the project is that the church (quite logically) doesn't have a wifi network. So we need to use a GSM or 3G connection.

High Power measurements by USB

By mvuilleu, in Measures, november 29,2013.

People often ask us whether we have a module to measure electric consumption on a high power system. Indeed, the Yocto-Watt is well suited to measure the power consumed by an electrical appliance, but its design limits the measurable power to 16A. This is not enough for example to monitor the global electric consumption of a house, of an industrial electrical installation of some size, nor of a three-phase electric system. Let's have a look at existing solutions for this type of applications.

Yocto-4-20mA-Rx: the answer to exotic needs

By martinm, in Measures, november 08,2013.

Customers regularly ask us whether we don't want, by any chance, to build a module to measure [insert a physical quantity here]. Sometimes, we jump into it, but we sometimes also decline because the resulting module would be too specific. Therefore, we would likely be unable to sell enough modules to amortize the development costs. We thought about the issue, and we think that we have a reasonable solution.
