U.S.-based Littlebird has released a toddler-tracking device that can provide parents with peace-of-mind when they leave their young children with caregivers. The ‘Littlebird CareTracker’ wrist-worn wearable also includes physiological sensors to monitor the child’s heart rate, activity, and sleep to provide regular wellbeing updates to both parents and caregivers.
The device is easily attached to a child’s wrist and is connected to the ‘Littlebird’ iOS or Android app on both the parent’s and designated caregiver’s smartphone. The Littlebird CareTracker employs Nordic Semiconductor’s nRF52840 Bluetooth® LE SoC to act as a wireless ‘tether’ between the child and the caregiver. In the event the child or caregiver moves out of sight or earshot of one another and the Bluetooth LE connection is lost, the device will automatically send an alert to the parent and caregiver’s smartphone using Nordic-powered LTE-M wireless connectivity. The alert also includes the last known location of the child based on GNSS coordinates.
“When I developed the Littlebird CareTracker I wanted to empower parents and caregivers through care transparency,” says Monica Plath, CEO and Founder of Littlebird. “Having two toddler boys who run off from time to time, I also needed to know who was with my child when I was apart from them.”
In addition to the nRF52840 SoC, the Littlebird CareTracker integrates Nordic’s nRF9160 low power SiP with integrated LTE-M/NB-IoT modem and GNSS to provide cellular IoT wireless connectivity between the wearable and smartphone app via the Cloud. The nRF9160 SiP combines LTE-M cellular network location data with GNSS trilateration for precise position monitoring of the device and child. The nRF9160’s assisted and predictive GNSS also saves power by speeding up time-to-first-fix (TTFF) on the satellites.
