The Smart Sock Plus comes with a sensor that actually does the monitoring as well as 3 fabric socks in different sizes so you can change them as they grow (with no extras to buy!!), as well as a base station. On the newer V3 sock, there is completely new hardware as well as changes in design. The new Plus version of the sock now fits babies from 5lb to 55lbs (approx 5 years) and the sock just pops onto the base station for wireless, drop-and-go charging – in fact, you can get an 8-hour charge in just 20 minutes or a full 16 hours in 90 minutes! The sock can also be worn under a sleepsuit or a sleeping bag.
The base station glows green to let you know everything is ok but notifies you with lights and sounds if the oxygen level or heart rate leaves the pre-set zones. The base station also transmits real-time heart rates and oxygen levels using clinically proven pulse oximetry so you can see live reading and notifications by using your smartphone (not included!). This is done using your home Wi-Fi system but don’t worry if your Wi-Fi drops, the base station still works! The smartphone app also allows you to see their sleep history too, so you can see patterns and adjust routines as they grow.
