The advancement of science and technology has contributed of realizing
the better life. Electronic technology is one of technology that has attributed in
human life, there are many practical and flexible electronic devices that has been
now, the river water level monitoring that conducted still using manual devices in
form as water level scale that placed at river side/bridge. The monitoring system
of water level in real time can monitor the water level continuously with
employing a sensor as detector in order to detec the range of sensor with water
surface. In its design, it used PING MB7066. Sensor as range sensor based on the
principle of voice wave reflection, which is the sensor is transmit and sensor
bounced ultrasonic wave, then measure the time different as its sensory base that
will processed by microcontroller Arduino Atmega2560.
The output from microcontroller can be displayed at LCD in a character
that able to understood generally and able to sending SMS from Modem Arduino
GSM Shield to user mobile.
