Abstract
Some areas in Indonesia are very gristle of floods. A solution to solve that problem is to make a device that able to measure the depth of water on some areas. The devices that can be used is Echo Sounder. The work principle of it is using ultrasonic waves, thus the waves will be sent from transmitter and then it will bump a barrier then be reflected to the receiver. The time of starting from transmitter until bump a barrier is half of time (1/2 s). The pulse of time from the receiver will be continued to the Microcontroller AT89S52 which is an Integrated Circuit that has 4 kilo byte of FLASH PEROM. The output of the measurement will be shown to the LCD display. The quantity methods that will be used is generate the pulse of Ultrasonic signal by the timer 555 and then send to transceiver. To put a result on a LCD, C programmed will submitted to the Microcontroller by downloader. The data will collect to check off the accurate of that Echo Sounder. So that the conclusion is Echo Sounder is very benefit to measure the depth of water.
