Abstract :
The monitoring system is now progressing along with the development of
technology. One of them is the increasingly rapid use of microcontrollers for its
applications in monitoring. The monitoring system is carried out aimed at being
able to monitor all activities or activities that occur in a particular room or area
that are considered important to be safeguarded. Water level monitoring can
provide information about water level conditions. A common method is to record
the water level through a sign or water level installed. If unusual conditions occur
in the use of water, it will become an obstacle in getting real time data that can
lead to late decision making. Because of this, the author designed a water level
monitoring and control tool using PC-based ultrasonic sensors detected by
ultrasonic sensors to measure water so that in real time it can determine the
height of the water level displayed on the PC
