- The data recording is possible on the water meter there is a difficulty because ofthe location of water meters that are inside the house or fenced because it is less practical inthe data on the water meter manually. Therefore, to facilitate the taking of data, designed atool that functions retrieve data from a certain distance. The tool is called The Automaticmeter Drinking water with Remote Mikrokontroller AT89S51, which has the core componentsmikrokontroller, A276 sensors, and serial RS232 converter to rs48. A276 sensor readeach round of magnetic fields on the vane rotated by the flow of water, each of the northmagnetic fields, sensors will high and is logic 0 because the sensor characteristics halleffectis active-low or 1 = 0. When mikrokontroller receive data from sensors, mikrokontroller beprocess and store any changes and the counter will display on the LCD, if there is a requestfrom the PC, mikrokontroller will be send data to your PC. Communication of data betweenthe transmitter and receiver is done with the rs485 to rs232 to PC. Programs that control themikrokontroller between the sensor inside the water meter is written using assembler language.
