In summer you have to be careful with the house if we go on vacation. My dream has always been to have a robot created by the [OCP](http://www.youtube.com/watch?v=A9l9wxGFl4k) who guard the house from thieves.
*Nacho Sanchez* from [fresymetal.com](http://www.fresymetal.com) send us to mail a new article that is sure to interest our readers: A motion detector with *Raspberry Pi*...
He surprise us before with an extraordinary tutorial about [intrusion detection on our network with the Raspberry Pi](https://misapuntesde.com/post.php?id=182) and now shows us the steps to put a sensor in the home door and when entering someone can send a message or perform some action.
Thanks for sharing the article, Nacho!
