Yah kali ini saya akan menjelaskan mengenai bagaimana cara membuat alat untuk memonitoring kecepatan air dalam m/s menggunakan water flow sensor, alat ini memiliki kelebihan yang diunggulkan yaitu dapat mengirimkan data ke internet atau web hosting sehingga siapapun, kapanpun dan dimanapun user berada, user dapat memantau kondisinya selama koneksi internet masih lancar, itulah kelebihan dari alat ini yaitu tidak kenal jarak. untuk lebih jelasnya berikut akan dijelaskan mengenai bagaimana program dan skemanya.
a. Arduino Uno
b. Water Flow Sensor
