dc.description.abstract | The purpose of making this essay is to apply CodeVision AVR in ATMega8535
for data processing liquid loading on the glasses automatically based on the height of
the glass and manually based on the input volume of fluid. In automatic mode, the glass
will be detected by a limit switch, then glass height measured by a potentiometer.
Furthermore, limit switches and potentiometers transmit the data to the microcontroller
to be processed. Then the microcontroller activate the water pump to dispense the liquid
into a glass. Filling the liquid inside the glass in the control by ultrasonic sensor HCSR04
that is adapted to the measurement results of high glass by a potentiometer.
In volume mode, after determining the volume of fluid, limit switches will detect
the presence of glasses and transmits the data to the microcontroller to be processed.
Furthermore, the microcontroller activates waterpump to dispense the liquid into a
glass. Filling the liquid inside the glass is controlled by a flow meter AGO A-7 in
accordance with the amount specified volume.
The test results in automatic mode indicates that the system is capable of filling
the liquid into the glasses automatically with an error of 1 cm. The test results show that
the volume mode system capable of filling the liquid into a glass with 30 mL error. | en_US |
