DIY Home Automation Box with Pcduino and Arduino

A DIY project that is a home automation box created with what as brains but pcduino and arduino combo. Nice! This home automation box allows the maker to turn on or off the lights in a room or select color of a hacked oil diffuser (the oil diffuser also created by the maker and made compatible to this project), project the indoor or outdoor temperature and humidity ratings from an arduino node by using RF transmission 433Mhz or create the simple handle for alarms. Like any other amateur DIY, this one too leaves plenty of scope for your imagination.
Here, LED is wired to pcduino for rx/tx data transmission; TX 433 is directly feeding pcduino – the ‘C’ environment is in use here which is known for rcswitch and manchester library. Arduino nano is linked with pcduino GPIO pins so that the usb port is available for adding more features, like, say a camera. The nodes are simple arduino pro mini with 5v and 3v for special case, that use Samsung Lion batteries. These give power to sensors like DHT22, brightness sensors and then throw the data every fifteen minutes. To conserve the battery power, they are put in sleep mode at all other times.

The hardware interface is done with the help of openhab(http://openhab.org).
