• SENSORSAFE CHEST CLIP: The Bluetooth-enabled SensorSafe chest clip sends alerts to your phone if your child unbuckles, the temperature becomes unsafe, or the child is left unattended. It can also notify emergency contacts and share your location if needed, for unparalleled peace of mind and safety.
