Drowning prevention system-at sea level

Abstract

Drowning is usually quick and silent. Media portrayal of drowning as a loud, violent struggle have much more in common with distressed unskilled swimmers, Drowning causes the third highest number of unintentional death. Many drowning prevention systems have been proposed however they are not suitable for implementation at sea level. Our target to abide a cryptogram lapse prevents drowning at the beaches. Two sensors namely oxygen sensor and water detector are used. Water detectors are placed in the locket. This is suitable for people who play at the shore; who don't go deep into beaches. If a person gets pulled into the sea by the waves, the water detector in their locket will be submerged completely and if the detector continues to remain submerged then an alarm is triggered through which the coast guards are alerted. Oxygen sensor used for swimmers and is placed in the armbands of the swimmer. Oxygen level in the sea and the oxygen level in the atmosphere vary drastically. If a swimmer is about to drown the oxygen level will constantly be around 80 per cent (which is the normal oxygen residue in the sea); Then the sensor triggers a floating aide and simultaneously alerts the coast guards. An underwater network is deployed with a modem at each network node. The sensors communicate with these nodes. Similarly, sensors are placed on the seabed to indicate sudden increase in depth. When a user is about to cross those sensors the controller alerts the coastguards and the swimmer.
