		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}
