		abstract={The development of monitoring a liquid surface is very useful in life, unpredictable natural conditions and changing weather conditions, so that natural disasters such as floods can come unexpectedly, although we cannot avoid natural disasters, but by making a surface monitoring system liquids, can be used as an early warning system or early warning system so that damage and fall in casualties in a disaster can be minimized, besides that this tool can be used as a monitor of a liquid surface that might endanger people's safety if measured directly like a chemical reactor. One of the opportunities for using technology to facilitate human work is a liquid level monitoring system that can be accessed wirelessly so that it does not waste time for manual use. Bluetooth is a data transmission technology using radio waves with a maximum distance of 10 meters, but the need for technology users is increasing, namely the transmission of data using radio waves (wirelessly) with a distance of more than 10 meters. So wireless technology is the solution, because through 2.4 GHz radio waves can send data more than 10 meters. In this study wireless technology is utilized in the process of sending data. Arduino Uno R3 will process the signal read by the HC-SR04 Ultrasonic sensor and display it on a 16x2 LCD. Display on 16x2 LCD sent to PC / Laptop through wirreless network using XBee S1. On display on PC / Laptop on display with the Arduino IDE application on the serial monitor.}
