Abstract. A prepaid water meter is a device for controlling the volume of
customer water usage with a water pulse system. Currently, the prepaid
water meter implements a card system as a storage area for customer water
pulse data by filling it via a keypad. This research aims to develop a prepaid
digital water meter using EEPROM memory as a storage area for customers'
water pulses by filling it with a remote control based on the AT89S52
microcontroller. The research method is carried out by developing hardware
and software, as well as testing the overall system performance. The results
showed that the prepaid water meter system has worked well to control the
work of the solenoid valve in adjusting the volume of water consumption
according to the number of water pulses in the EEPROM memory. Also, the
system has worked well in the process of recharging water pulses on prepaid
water meters via remote control.
