How to use Yoctopuce modules in the middle of nowhere

By Sébastien Rinsoz, in Measures and Android, march 27,2014.

courtesy of @lain GHow to measure environmental factors (temperature, light, humidity, ...) in a field located kilometers away from any electric socket and any Wifi network? The first solution coming to mind is to use an Android phone and to connect Yoctopuce sensors by USB. This solution works (as illustrated here), but to power this type of installation, you need to use a solar panel and a battery of a relatively large size. To perform some measures for a relatively short period of time (a few weeks), there is a simpler and probably cheaper alternative: using a Wifi connection between the phone and the sensor instead of a USB one.

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

By mvuilleu, in Measures, january 10,2014.

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.

Yoctopuce, get your stuff connected.
