Humans make mistakes. It's who we are at the end of the day. One consequence of human error is that an average of thirty-seven children die every year from being left behind in cars in the United States. Our goal with this project is understanding this mistake and limiting the consequences. Being a parent is a non-stop job with a tough set of responsibilities and from time to time parents tend to make mistakes. To make their job easier, our design team is creating a product that notifies parents if their child is left behind in a vehicle. The product is comprised of two devices: a primary device that stays in the car and a secondary device that the parent carries. The primary and secondary devices are a modified car seat belt buckle and a key fob, respectively. The devices communicate between each other to inform the parent of the current inside temperature of the car and if their child is present in the vehicle. The devices are able to stay connected at a reasonable distance and alert parents when connection is about to be lost. A sensor located in the primary device will be activated if the car seat is buckled when the car is turned off. In this case a child remains in the car and the key fob will vibrate and ring to alert the parent. If the parent purposely left their child to run a quick errand, they can dismiss the message. The primary device will then measure the inside temperature of the car continuously and alert the parent when the temperature becomes life-threatening. If no action is taken within a certain time period emergency personnel will be alerted. In the end, this product will hopefully help us keep as many infants safe as possible.
