The Rasberry Pi has inspired a lot of people to create unique fixtures and devices for their homes. Like this one, in which a gentleman in Ireland decided to take care of his new pup’s early-morning potty break needs with a bit of Pi-based DIY bark-activated home automation and a lot of ingenuity. Yes, I said bark-activated. Following in the footsteps of voice-activated automation solutions like VoicePod and the new ivee, he created an automated door opener based on his girl’s particular woofing habits and schedules:
She barks at night when she’s left out. She barks early in the morning when she’s left in. So once I recognized the patterns of her barking, I realized that all I needed was something that would let her out when she needed to go for a pee, usually around 6:30 in the morning. I could do this with a timer switch and a door strike, but where’s the fun in that?
I wanted this to be an educational project, so I decided I’d use the Raspberry Pi again, this time for a non-camera related project. And I decided on a bark activated automatic door opener…
It involves a bark detector (noise detector circuit) wired to the input of the Raspberry Pi so that it can detect the barks. A motor driver circuit to drive the actuator that unlocks the door, and a weight/pulley system that swings the door open when its unlocked.
The hallmark of a good home automation system is that it should adapt to your specific lifestyle, and what better example than this?
All the parts and the code for the bark-activated Rasberry Pi program are at the source link, so if you’re looking for a weekend project and have an independent pooch with a kooky schedule, this certainly is a high-tech alternative to a doggie door.
