Perancangan Alat Pengisi Cairan dalam Gelas Secara Otomatis Menggunakan Sensor Ultrasonik & Sensor Hambatan Geser Berbasis Atmega8535

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.
