Drowning:
Drowning:
Drowning is death caused by the inability to swim
More than 320k drowning deaths occur annually
Of these deaths, children are more likely to drown
80% of child drownings happen while an adult is nearby
Adults are unaware of when it happens
The Solution:
The Solution:
The best way to allow the adults to become aware of when drownings are happening is to alert them.
This can be done through an alarm that can detect the drowning and tell the adult.
Challenges:
Challenges:
The circuit will fail to work if contact is made with water
I could use a 3d printed box to cover it
A regular microphone performs worse underwater
I could use a hydrophone, which is designed for the same function, but underwater
Differentiating between which swimmer is struggling
Using a different frequency to identify each one
Parts:
Parts:
A small computer with a built-in accelerometer to detect if someone is in distress.
The transducer makes the frequencies.
Used as the battery
Used to make the sounds from the transducer travel through water better.
Used to interpret the frequencies made by the transducer.
Alerts the lifegaurd/guardian on land.
Used to connect the Raspberry Pi to headphones
A microphone and headphone splitter.

Alerting
The flow:
The user downloads an app to unlock the functions for the project
The detecting part tracks the movements of the target
Casing used to prevent the software from getting wet/destroyed
If the detection mechanism detects drowning(with the use of code), the alarm will go off and alert the user of the target’s drowning with audio
