Understanding How the Owlet Smart Sock Works

Understanding How the Owlet Smart Sock Works


Traditional baby monitors transmit sound from one room to the other, or step up the game to transmit video from your bub’s nursery to your room. Here at Owlet, we wanted a baby monitor that did a little more. Being parents ourselves, we trust our eyes and ears, of course, but sometimes sights and sounds don’t communicate everything that could be going on with babies.


We worked, and built, and tested – just to re-work, re-build, and re-test to make a baby monitor that offers a better picture of what is going on with our babies. Is there anything cooler than being able to open up an app and see what’s going on in the news, or the weather, or with your beloved footy team? We don’t think so: technology has brought all of our favorite things to our fingertips. It really makes sense to use technology to make one of the hardest jobs in the world a little easier, doesn’t it?


Check on your little one without disturbing their sleep. Using pulse oximetry, the Owlet Smart Sock tracks your bub’s heart rate and oxygen levels and sends real-time insights to your phone. The Smart Sock is designed to grow with your bub which is why it comes with three different fabric sock sizes that comfortably wrap around your bub’s foot. 

It also includes a Base Station which glows green to reassure you your bub is okay but will notify you if heart rate and oxygen levels leave preset zones. The Base Station was designed with different notifications, including notifications for heart rate and oxygen falling outside of range (red), Bluetooth disconnect between the Smart Sock and Base Station (blue) and inability to get a proper reading (yellow). Learn more about these different notifications on our website*Always remember to contact your pediatrician for any specific questions you have regarding your bub.


Knowing what your bub needs and when they need it is a cause for stress and anxiety with most new parents. As one of the pioneers for in-home monitoring of infants, we felt a big responsibility to provide superior technology and peace of mind for parents. A recent study in Global Pediatric Health showed that not only do 96% of parents using the Owlet Smart Sock feel less anxious but 94% of parents report better sleep quality.

Our mission at Owlet is to provide better care access for babies in the home by empowering parents with the right information at the right time. The Owlet Smart Sock gives parents peace of mind and allows you to check in on your little one while they’re sleeping so you too can get some rest. Because when you get the sleep you need, your bub gets the mum and dad they deserve and that’s priceless.
