Home automation made easy with the help of Raspberry Pi and Arduino

Everybody knows that good things happen when you pair a Raspberry Pi with an Arduino, which includes everything from a Star Trek-like tricorder to a kegerator interface. One Instructables user (Electronichamsters) decided to take the boards and design an extensive home automation platform that’s able to monitor just about everything inside and outside of user’s homes.

Instead of using the boards for simple things such as automated blinds or lights, Electronichamsters ‘Uber Home Automation’ platform can monitor for water leaks, loud noises and even alert users when the mail arrives. His design makes use of a series of cheap wireless sensor nodes (PIR, heat, light, sound, etc.) that can be placed anywhere and on anything that needs monitoring. Those nodes relay the data to a wireless gateway and an Ethernet gateway (an Arduino Uno), which in turn sends the data to the Raspberry Pi.

The RPi then uploads the data to the internet where users can monitor using their smartphones. It even sends alert emails when something is amiss, allowing users to view the issues through a web cam. The whole setup costs a little over $270, assuming users already own a Raspberry Pi. Those that want to see the build process can head over to Instructables, which has a detailed list of parts and code to get things up and running.

Ahh... the adhoc project enclosure... It may look crude but this sound sensor is very effective and can be placed anywhere
