They invented an AI cat doorbell that only opens the door for meows, and you can do it yourself with a Rapsberry Pi.

owners cats those who live in houses with an outdoor garden and no traffic usually let them out for a little run. At the risk of coming home with a glove or scarf from a neighbor…

Many of them put cat slams on the door but not recommended, as another animal can sneak in, and even thieves. Although there are already smart cat shutters that open only when a dog or cat is detected.

The solution is called Cat doorbell, do-it-yourself cat doorbell Created by Tennis Smith. This is a doorbell that uses Raspberry Pi and artificial intelligence to detect a cat meowing near the doorbell, and send SMS to the owner of the house to open the door.

Technically, the doorbell cannot open the door, only notify the owner through a notification, although it shouldn’t be too hard to send that notification to the Amazon Echo software connected to the smart doorbell to have it open the door automatically. The good thing 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 sounds.

cat doorbell It is an Internet of Things (IoT) application based on Amazon web service (ABC). Amazon has an IoT Core service on AWS that detects Raspberry Pi when connected. The AWS software is loaded onto the Raspberry Pi that has a microphone connected to it.

There is a small machine learning application on the Raspberry Pi called Tensorflow Light. Along with Tensorflow, he has a small database of sounds that he can 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 the 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 you from changing the meow of a cat to a barking dog… You have all the step-by-step instructions on GitHub.
