I want to implement a small project but I need your guidance please, I want to build a smart car children safety system, we faced a lot of cases were children have forgotten in cars or school buses which lead to suffocation or bad breathing and may cause death as well.
My idea is to fix motion (PIR) sensor or thermal sensor in the roof of the car or school bus so if the car has turned off and locked then this system will activate and will looking for any motion or hot body inside car, if so then it will activate car’s horn, flash light to immediately attract driver attention, furthermore I want to develop mobile application linked to Arduino board so if this system activated then immediately a notification will received through application informing that there is a child inside the car along with location, moreover if no body open the car and temperature rises then automatically windows will open to allow fresh air ventilation and door’s lock will unlock, I want to fix also a camera unit which I can access to see car or bus inside through mobile application.
So for this project I will need:
Arduino board (IOT applicable)
LTE shield with sim card
GPS tracking shield
PIR sensor
Thermal sensor
Camera unit
Temperature sensor
The problem is there are a lot of Arduino models and a different GPS shield so could you guide me for best selection of Arduino and remaining shields and sensors ??
FYI, I need to connect Arduino to internet through LTE shield not GSM shield, I want Arduino board which is easy to do IOT on it, I need it also to interconnect with car’s windows, horn, flash light, door lock.
If you need further information, please request it from me.
Whatever creates a moving shadow where PIR sees will trip the alarm.
A bird or person or fast moving cloud could.
I suggest using different sensors in concert (PIR + Ping + I dunno) but I think that the real problem is implementing living on the run turning minds off as normal. Who else has no time to make sure no child is left behind but someone pushing along? Oh we can't take the time out of our important busy lives to notice we don't have the kids like in a comedy! I know, lets get a device to take the responsibilty? We could be even more shallow!
You really need to begin your system by consulting the school bus manufacturer. You will never be allowed to put a home brew device in a real school bus. Only the manufacturer will have the ability to do that. Besides, if your system fails to detect a person left on a bus, what will your liability be?
Nope....Arduino not allowed for use in such circumstances.
Rather make people responsible for whatever...don't rely on "electronic devices" to do your job for you.
Basically, you are starting at the wrong end and working backwards.
Look at the modern 60GHz and 24GHz presence sensors. A device such as the 60GHz Aqara FP1 can detect the tiny movements that result from breathing.
In theory a device that connects to the vehicles CAN bus can send commands to open the windows and unlock the doors. This type of integration will need to be customized for every model of vehicle.
