RANCANG BANGUN ANEMOMETER BERBASIS AKUISISI DATA

Data acquisition system is aimed to display value and graphic in real-time. It is designed on Anemometer to present value or graphic of wind speed on Personal Computer (PC) that furthermore, data is analyzed and stored automatically in Microsoft Excel. Equipment used is Wind Speed Air Velocity Anemometer in the form of fan to measure wind speed. It is designed by using Optocoupler as transducer connected to Arduino Uno ATmega328. This Optocoupler has integrated phototransistor and LED (Light Emitting Diode) components. Both components functioned as receiver and data transfer of wind speed from fan by 0 and 1 logic value. Obtained data by PC will be shown on table and graphic including complete time. The result of test shows accuracy specification of Anemometer in 96,149 % and 1,619 % precision with average deviation standard of 0,0475
