Trackable and Multipurpose Life Jacket

In today's world, defense power is an important factor in any nation's security. Soldiers being the backbone of any armed force usually lose their lives due to lack of medical help when in emergency, also soldiers who are involved in missions or in special operations get straggled on war fields and lose contact with the authorities. So for their security purpose, many instruments are mounted on them to view their health status as well as ammunitions present. We have used various sensors such as temperature sensor, pulse rate sensor, gas sensor, etc. These sensors will monitor the health status of the soldier whenever required. Also using GPS we can track the soldier's exact location whenever required. Using oxygen level sensor we can also monitor the environmental condition, so authorities can provide essential aids. The communication is established between the soldiers and authorities via GSM. Any abnormalities in the readings of wireless body area sensor network (WBASNs) is considered as a trigger for GSM to establish the connection between the soldier and base unit and send current location and health status to the receiver. So by using these equipment we are trying to implement the basic life-guarding system for soldier in low cost and high reliability.
