They invent an AI doorbell for cats that only opens the door to meows, and you can do it yourself with a Raspberry Pi

When a cat wants to enter the house, it is in charge of letting you know. Let an AI warn you, to open the door.

the owners of cats who live in houses with an outside garden, and no traffic around, usually let them out to run around a bit. With the risk of coming home with a glove or a scarf from the neighbor…

Many of them put cat flaps in the doors, but it is not recommended, because another animal can sneak in, and even thieves. Although there are already smart cat flaps that only open if they detect a dog or a cat.

Another solution is to use Cat Doorbell, a DIY doorbell for cats Created by Tennis Smith. It’s a doorbell that uses a Raspberry Pi and artificial intelligence to detect the meows of a cat near the doorbell, and send an SMS to the owner of the house, so that he opens the door.

Technically the doorbell can’t open the door, only notify the owner by means of a notification, although it shouldn’t be too difficult to send this notification to the Amazon Echo software connected to a smart doorbell, so that it automatically opens the door. The good thing about this is that it works with any garden gate.

The most interesting thing about this project is that it uses artificial intelligence and Amazon services to detect meows among any other sound.

Cat Doorbell It is an Internet of Things (IoT) application based on Amazon Web Service (AWS). Amazon has an IoT Core service on AWS that detects a Raspberry Pi when connected. The AWS software is loaded onto the Raspberry Pi, which has a microphone attached to it.

You also have to install a small machine learning application called Tensorflow Lite. It contains a small database of sounds that it is able to identify. When the correct sound (in this case a cat’s meow) is detected, Tensorflow recognizes it and sends a message to AWS.

AWS IoT intercepts the message and sends it to an AWS Lambda function for formatting. The Lambda function then forwards the message to a Simple Notification Service (SNS) which sends it as an SMS text message to the mobile phone.

East doorbell for cats It’s not hard to build, and it’s pretty cheap. And nothing prevents changing the meows of a cat for the barks of a dog… You have all the instructions step by step on GitHub.
