  • 摘要:Almost every year the capital city of Jakarta experienced flooding, floodingcaused by high rainfall which increases every year and many people who throwgarbage in rivers. Systems that used to be very simple, namely by looking atwhat height the water has reached maximum or not. If it reaches a maximumthen the guards would open the floodgates, how to open the door the water wasstill manually, ie by turning the lever. So the writer think of an alternative thatcould be used to reduce the occurrence of floods again is "Altitude WaterDetection System." Water height detection system uses four sensors andwater using AT89C51 microcontroller as the processing of data from the inputreceived from the water sensor. Initial state of this system is going to sevensegment digit appointment in 1995, when the water first touched the watersensor, the seven segment displays 96 digits.. the first buzzer-yi will berbunwhen the third water sensor has been touched by water, the seven segment willalso feature 98 figures. the buzzer will sound when the water sensor is alsofourth touched by water, the sevent segment digit displays 99 and dc motor willrotate. Dc motor will stop when the switch is pressed. When the water has beenreduced because of the dc motor rotates, the sensor of the fourth water will notget wet again. So the seven segment displays 98 digits and the second buzzerwill stop ringing. At the third sensor is also not exposed to water longer thenseven segment displays 97 digits and the first buzzer will stop ringing. At thetime of the second sensor tersenuh no longer water, seven segment displays 96digits. so well at first when the water sensor is not touched by water, dc motorswill move and will stop when the switch is in the press and seven segmentdisplays 95 digits.
