Connecting sensors to Microsoft Azure

By mvuilleu, in Internet of Things, july 10,2015.

We have shown several times how an autonomous sensor can send data through the Internet to a program hosted on a web server. But, until today, we limited ourselves to the most classic development environments for web servers: PHP, Java, or Node.js. Today, you are going to see that it's also easy to send data to a Microsoft Azure data base, enabling us to access it from the new Microsoft ecosystem.

Using Emoncms on a private server

By seb, in Measures, june 10,2015.

A few months ago, we explained how to configure a YoctoHub or a VirtualHub to automatically post sensor values on emoncms.org. Emoncms is a web site which allows you to store measures in the cloud and to display them prettily. There are numerous sites which offer this kind of services (either free or for a fee), but Emoncms is, to our knowledge, the only one which is Open Source and which can be installed on a private server. And this is exactly what we are going to do this week.
