A car seat is designed to ensure that a parent does not forget a sleeping child in the back of their car. According to Arizona Central, more than 800 children have died of heatstroke as a result of being left in hot cars since 1998. Arizona is the fourth-highest number in the country behind only Texas, Florida, and California There are two sensors in the car seat. The first one is located directly under the child. The purpose of this sensor is to detect if the seat is being occupied by a child. The other sensor detects if a fob key is 10 meters away from the seat. If the key is over 10 meters away, the sensor will give a high reading. If the key is less then 10 meters away, the key will give a low reading.
