The Sensorsafe Safety Technology

Peace of mind for you. Better safety for your child.

Attached to the harness system of your car seat, the SensorSafe clip connects to your smartphone and provides essential alerts to help prevent critical situations: when your child unbuckles the clip, when the ambient temperature of your child is too hot or too cold, if your little one is left unattended in the car, and if your child has been seated for too long.

51% of parents reported that their child had unbuckled themselves from their car seat.
