ABSTRACT:
The design and implementation of an automated liquid
observation and controlling method utilizing an affordable liquid flow sensor
and the microcontroller are presented here which has the ability to assist the
health care provider to control the saline circulation rate using Matrix keypad
or Android phone. The Arduino Mega (2560) platform has been used as controlling
unit for providing necessary control along with a 3×4 matrix keypad and
Bluetooth module to control the drop per minute manually and by using an
android phone. The designed flow sensor will be hooked up to the drip chamber
of the saline container to determine the saline flow rate as well as an
accurate
number of a drop of the saline. The obtained outputs from
the sensor are continuously checked with the given command and if any mismatch
is found, the microcontroller moves the servo motor to modify the circulation
rate to balance with assigned command. The device has been tested after
completion of necessary hardware development. The outcome is satisfactory which
indicates a possible application in taking care of patient more appropriately.
