The system is used to measure the pressure and the temperature values up to hundred meters of the sea water. This project is also called as expendable environmental probe. The probe contains a temperature sensor, a pressure sensor, and system electronics. It is needed for the calculation of the performance of the sonar of warships, oceanographic institutes and oceanographic purposes. The probe include the sensors which developed by using Micro Electro Mechanical Systems technology. The probe is an expendable probe capable of reaching over hundred metres of depth when dropped from a moving ship, and a thin conducting wire is transferred through the data to the ship. This data is collected, stored, and displayed the data acquistion system. Data was collected from the temperature and the pressure sensors but the data could not displayed the data acqusition system with one wire system. One wire system is used only a few meters but I want to communicate the system up to hundred meters. Therefore I decided to use two wire system with communication module. In conclusion, the system was prepared in conformance with hardware design and the communication system was changed with two wire system design.
