In the U.S. about 40 children die each year because they are left alone in a hot car. It’s an extra risk for babies in rear-facing car seats, because they’re not visible to the driver. SensAlert, a removable car-seat insert by car-seat maker Doona, uses sensors to detect the presence of a child to help prevent tragedy. New to the U.S. market, it automatically connects to smartphones via Bluetooth, and triggers three incremental alerts if a child is unattended in the car.
