Development of a Smart Wearable Anti-drowning System

Abstract

Drowning is one of the major causes of unintentional death in the world. owning to this reason, there is a need to curb the issue of drowning. some systems have been developed over the years, but most of the systems are not accurate in detecting a drowning person and do not provide an effective rescue scheme to prevent the swimmers from drowning. The smart anti-drowning and alert system is a system which detects, rescues the swimmer experiencing drowning and alerts the necessary authorities. The system uses two sensors, pulse sensor and accelerometer for the detection of the heartbeat rate and tilting pattern of the swimmer. The Arduino Nano microcontroller receives analogue signal from the sensors and sends a signal to trigger the air vacuum pump and sends a message, when the threshold value is met. The threshold value of the pulse sensor is 45bpm-150bpm (minimum and maximum value) while the threshold value of the accelerometer is 750 -1100 (minimum and maximum value).
