From the Forums: Dog Door Sensor Built with AdaBox 003 & 004 Components

Thanks to forums user stevenquinn for sending this in!

Just wanted to share a project that’s been in the works that’s finally working, using Adabox 004 plus the feather from Adabox 003, along with the Adafruit LIS3DH (https://www.adafruit.com/product/2809). My wife and I trained our dog to ring a set of bells at the back door when she needed to go outside. Problem was when we moved to a smaller place and let her have free run at night, the sound of the bells just wasn’t loud enough to wake us up at night, and we had a few accidents. So I decided to make something that’s a little louder and doesn’t get set off when our cats are just walking around at night (i.e. no proximity sensors).

This ended up having 3 parts to it: a sensor by the door to tell when the dog needs to go out, another board to act as a receiver and play a message, and a small web app to act as a go between the two feather huzzah boards.

The sensor by the door hangs from the set of bells she already uses. It uses the Adafruit LIS3DH accelerometer to detect when she bumps it with her nose (took a lot of trial and error to get it to trigger easily but not go off randomly). If it detects a bump, it makes an http request to my web app.

On my night stand, I’ve got the board / speaker from Adabox 004 setup. Every 5 seconds it does an http request and pings my little web app to see if there’s been a hit at the back door it hasn’t read. If there is, is plays track001.mp3 which is a recording of “Kona needs to go outside” that loops a few times, and lets the web app know to mark that entry as “read” so it won’t do it again. I could’ve just only stored one “hit” at a time, but I figured it’d be interesting to go back and view old data. Since it was going to be hanging out on my nightstand, this one also got a nice 3d printed case to house it as well.

Just wanted to share! Definitely over engineering the problem a bit, but it was a lot of fun and nice to find an every day use for some Adaboxes.
