The last few years have seen an incredible increase in the marketing for home automation devices. Why this tech is just picking up now is something we’ll never understand – home automation systems have been around for decades, mostly in the form of security systems. For his Hackaday Prize entry, [IngGaro] is building an Arduino-based security system that does everything you would expect from a home automation system, from closing the shutters to temperature monitoring.
[IngGaro]’s system is built around a shield for an Arduino Mega. This shield includes connections to an alarm system, a GSM modem, temperature and humidity sensors, an Ethernet module, and IR movement sensors. This Arduino Mega attaches to a control box mounted near the front door that’s loaded up with an LCD, an NFC and RFID reader, and a few buttons to arm and disarm the system.
This project has come a long way since it was featured in last year’s Hackaday Prize. Since then [IngGaro] finally completed the project thanks to a change in the Ethernet library. It’s much more stable now, and has the ability to completely control everything in a house that should be automated. Now all [IngGaro] needs to do is create a cool PCB for the project, but in our opinion you can’t do much better than the mastery of perfboard this project already has.










The enclosure for this project was initially printed in PLA, the parts glued together and finally filled for a nice, smooth finish. [Chris] says PLA was a bad choice – the low melting point means the heat from milling the face plate gums up the piece. In the future, he’ll still be using printed parts for enclosures, but for precision work he’ll move over to milling polystyrene sheets.

The data pushes out to the Thingspeak server which handles pushing data out to the bigger network, and data representation (like the cool Google gauge in the picture). The best part: [Vegard] gets a phone notification when he accidentally leaves his soldering iron on. How perfect is that?
