The analysis mentioned health services within the role of medicine and life support. Underwater communication is needed in several applications like transfer of messages and speech transmission between submarines Ships, aqualung different etc., and additionally to trace lost ships and find sunken planes. The designed system was a system ready to offer data on the user's health condition, during this case, a live of pulse and blood heat employing a pulse device (finger-tip sensor). It took the info from the blood flow on the forefinger for sixty seconds, then displayed it on the alphanumeric display. The LM35 temperature device was used for blood heat information assortment. Changes within the device heat would be born-again into electricity, translated into digital type through a 10-bit ADC, processed by the PIC microcontroller, and displayed on the alphanumeric display. the complete system consists of two components, the on top of Water unit, and also the submarine unit for oceanographers model. The system realizes the dominant of the submarine model to attain numerous styles of movement once the antenna is three meters on top of the water. the space error, time error and speed error all meet the wants .The whole system operates merely and functions well.
