AI automatically preps a bottle when the baby cries

Bottle prepping machines make life just a little bit less hectic for overwhelmed parents, but they do still need to be started and that is easier said than done when you’ve got a wailing baby in your arms. That’s why Manivannan created this edge AI-powered system that automatically starts a bottle prepping machine when it hears a baby crying.

Manivannan designed this project to work with a Tommee Tippee bottle prepping machine, but you should be able to apply the same principles to any machine that starts with a single button or switch. An Arduino Portenta H7 board starts the machine through a DFRobot Gravity relay module. The only hardware modification required is connecting that relay in parallel with the machine’s start button.

The crying baby detection magic happens with a machine learning model running directly on the Arduino — no internet connection or cloud service required. Manivannan trained that model using Edge Impulse by recording both normal room noise and the baby crying. Manivannan’s tutorial explains how to perform the training so the model can recognize the difference between the two.

After training, the Arduino will constantly listen for the sound of the baby crying. When it hears that, it will automatically activate the bottle prepping machine, so formula is ready in a couple of minutes and you can concentrate on soothing the baby.
