Make an alert system for kids and pets trapped inside cars using Intel Edison Board. via instructables
On average, 38 children die in hot cars each year from heat-related deaths after being trapped inside motor vehicles. This system is meant to alert a parent if they forget their child in the car, m main design criteria for the system are:
1- No action is required to activate / deactivate the system. It is meant to “just be there”. The reason is that a parent who is running late or stressed out enough to forget a child in the car isn’t likely to remember activating / deactivating a system.
2- It’s not too noisy, if the system gives too many false alarms parents will end up disabling it.
The system works by monitoring CO2 levels in the car, CO2 is actually a very good indicator of the presence of people. The system will check CO2 level over N intervals, if CO2 level is continuously going up or if it gets past a certain threshold this is a sign that someone might be trapped in the car. Once detected a message is sent to all saved parents alerting them that something might be wrong. The message also includes information about location and temperature in the car.
