Starfish is a weight-activated seat sensor that notifies your smartphone when you’ve left a certain area – say your car –without your child. Starfish uses Bluetooth to pair with your iPhone or Android phone, and it fits snugly in your child's car seat. When you place your child on Starfish, the device automatically pairs with your smartphone, sending you a notification that your child is in his or her seat. When activated, Starfish then creates a “geo-fence” radius around itself. If you leave the “geo-fenced” area (around 20 feet), Starfish will automatically notify you that your child may be in danger. As an added layer of protection, Starfish can notify your emergency contacts if you haven’t responded to the notification after 5 minutes.
