BLOOD ~OLLER MIXER DILENGKAPI DENGAN PENGATURAN KECEPATAN DAN PENGATURAN WAKTU DILENGKAPI BATTERY CHARGE BERBASIS MIKROKONTROLLER AT89s51

Abstract

Blood roller mixer is device can be used to mix bloodin orderto achieve a homogeneous state so can
prevent the lysis 0/ blood, air bubbles, blood clots that can clog the Hematology Analyzer. There is some
cuvvets that the contain are blood and anticoagulant will be mixed/or 15-20 minutes. This tool uses two
volJagesources apart/rom PLN also use the battery as a volJagesource replacement if the power turn off in
order to avoid the blood is drying out The operation of this tool is when ON pressed, LCD will initialize and
press the time and speed selection. After that press enter key and motor will rotate. If the process has been
completed,motor wUI stop rotating and the buzzer sounds.
The importance analyst/or mixing blood in order to achieve a homogeneous state is the reason to
create this module. With the existence 0/ this module, the analyst can directlyset the time and speed as needed,
there is a battery as the voltagesource when the power is turn off.
From the description, author try to complete blood roller mixer tools that already exist with time
setting 15-20 minute and speed of the motor 40 and 46 rpm with battery charge equipped microcontroller
AT89S51 that will be dispJayedon the LCD.
