Abstract

Automatic water pump control. which is often called water level control (WLC) is a
widely used equipment both in housing, offices and in industry. Most commonly used
automatic water pump control systems are generally connected directly between the
water level detector and the ON / Off control of the water pump. This conventional
WLC system has a disadvantage if the location of the water pump and the water tank
are far apart even some floors so that the installation between the water pump control
and the level detection sensor becomes difficult
In this research, a prototype of automatic wireless water pump controller is made
between the water level detection unit and pump control is connected wirelessly via
radio frequency. The l water level signal is processed by AT Mega 328
microcontroller to decode ON or OFF sent through 433Mhz RF radio. The
advantages of wireless WLC e system that is the installation of the control unit and
the detection unit of water level easier even though located on different floors other
than that the control system can be moved location when needed.
From the results of this study it is found that the control of the water pump can work
automatically even though the distance between the level detection system on the
water container tank is located more than 20 meters from the water pump control
unit. . The distance between the level detection and pump control units can be
increased in distance by replacing the radio transmissions with greater power
