While many parents would never dream of being so negligent to leave their kids in a hot car, mistakes can happen and the technology is another preventative measure to ensure the safety of society’s most priceless and precious people.
This is similar to how seat belt sensors work, in if there is a weight in the seat and the belt buckle is not inserted into the receiver, an alarm will chime.
And perhaps a weight sensor in the car seat is an improvement that Evenflo can look into. If there is a weight in the baby’s seat (8-35 pounds), sound the alarms if the car is off. Alert the driver’s phone with texts and set off the external alarms.
