Raspberry Pi Cat Doorbell Listens for Meows
Wondering what crazy antics cats could get into if they had thumbs is its ordeal but upping the stakes with the ability to knock on doors is finally within reach thanks to maker and developer Tennis Smith’s Raspberry Pi-powered IoT cat doorbell (opens in new tab) project. It works just like it sounds, allowing his cat to notify him when it wants to go inside the house.
The system involves using a microphone to listen for potential meows. So instead of knocking, all the cat needs to do is what it does best—bellow out in desperate hopes of getting let inside. The Pi is responsible for detecting meows from other sounds using AI. If a meow is determined to have occurred, it sends a text message to Smith’s phone alerting him of the event.
The doorbell operates as an IoT device using Amazon Web Services (AWS). The Raspberry Pi can interpret potential meows using Tensorflow Lite, an open-source machine learning tool that you can train with custom models for projects like these. If Tensorflow detects a meow, it notifies AWS to initiate the text message.
The Raspberry Pi is housed by the door and connected to the microphone using a CAT5 cable with the help of a USB to RJ45 adapter. The doorbell is a small box placed outside cat-level and contains the mic. There are holes in the bottom of the box to help the microphone pick up the kitty pleas.
The code for this project is entirely open source and free for anyone to explore. It was written by Smith using Python and integrates with the AWS CLI. If you want to recreate the setup, you will need an AWS account. Smith provides additional details at GitHub explaining how to configure AWS for the cat doorbell.
