Membuat Anemometer dengan Arduino

Membuat Anemometer dengan Arduino
 

        Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat mengukur kecepatan angin atau anemometer, alat ini menggunakan arduino dan interface yang dipakai adalah lcd 16x2. di alat ini juga dilengkapi dengan sebuah buzzer agar saat kecepatan angin melebihi batas maka akan membunyikan buzzer tersebut untuk lebih jelasnya berikut adalah komponen dan programnya.

    rps = float(rpmcount) / float(timemeasure);         // rotations per second
    rpm = 60 * rps;                                     // rotations per minute
    omega = 2 * PI * rps;                               // rad/s
    velocity_ms = omega * radius * calibration_value;   // m/s
    velocity_kmh = velocity_ms * 3.6;                   // km/h
