SYNOPSIS ON WATER LEVEL INDICATOR

Department of Embedded System CETPA INFOTECH PVT. LTD

Water level indicator are ideal for dams,swimming pools and other such places where a specific water level should be maintain . This project is design for measuring and controlling water level. A microcontroller and level sensor IC lm 1830 is used in this to control the and measure the water level.

The code is written in assembly language microcontroller runs with 11.05mhz crystal

Features :

Easy to use. Stand alone device – no computer or any other hardware required. Needs to be programmed only once. Easy to program.

Benefits:

No manual intervention Easy programming with the help of manual.

In this project we try to give the same prototype for this type of water level indicator. For this AT 89C51 microcontroller and DS 1850 IC has een used.

LM 1850 is a water level sensor chip which isused to sense the level of the water.

When water level exceeds a specific limit buzzer rings.
