Development of Embedded Altimeter for Under Water Application

Abstract

There are presently many research related to water depth measurement system with high ratio of capability, low price and all of them are ended at Ultrasonic Range Finder. A suitable method to determine water depth and object detection is described in this paper. In this project we used an ultrasonic transducer.  Ultrasonic detectors can be used to find water depth and which is placed on the surface of water. Here we measure the time between the pulse transmitted from the transducer and the echo pulse received back. If a pulse transmits through water cause attenuation to avoid signal distortion and attenuation here we develop an amplitude booster circuit.  It also provides real-time feature to an RTOS enabled long distance remote access. Create a web page and data displayed in it and access the data using IP address and control the transmission of sound signals by the buttons created in the web page.
