    Abstract
    Pengukuran curah hujan diperlukan untuk berbagai hal kebutuhan khususnya dinegara tropis seperti indonesia. Penelitian ini bertujuan untuk melakukan rancang bangun alat ukur intensitas curah hujan berbasis kamera dengan memanfaatkan esp32 cam untuk menangkap gambar dan merekam video curah hujan. Penelitian ini bertujuan untuk merancang model pengembangan alat ukur intensitas curah hujan, memahami prinsip kerja alat deteksi intensitas curah hujan, dan mengetahui histogram dari rekaman video intensitas curah hujan yang dihasilkan pada alat deteksi intensitas curah hujan. Penelitian ini terdiri dari beberapa tahapan diantaranya yaitu tahapan studi literatur, perancangan alat dan komponen penelitian, perancangan sistem, pembuatan atau perakitan alat, uji coba semua komponen, program dan uji rekam layar dan tangkap gambar. Pada penelitian telah berhasil dirancang sebuah alat pengembangan alat ukur intensitas curah hujan berbasis kamera telah bekerja dengan baik dan model rancang bangun pengembangan alat ukur intensitas curah hujan yang telah di buat pada penelitian ini yakni ketika air mengalir melalui shower maka akan terjadi curah hujan. Proses terjadinya curah hujan akan ditangkap dan direkam oleh mikrokntroler esp32-cam yang diakses melalui perangkat komputer. Percobaan yang dilakukan pada penelitian sebanyak sepuluh kali percobaan, dengan rentang waktu 60 detik tiap percobaan serta pertambahan curah hujan setiap menit, data tersebut diolah melalui software phyton dalam bentuk histogram (Grayscale), yang akan dianalisis dengan metode analisis fourier transform
     
    Rainfall measurement is needed for various needs especially in tropical countries like Indonesia. The aim of this research is to design a camera-based rainfall intensity measurement instrument using the esp32 cam to capture images and record rainfall videos. This study aims to design a model for developing a rainfall intensity measurement tool, understanding the working principle of rainfall intensity detection tools, and knowing the histogram from a video recording of rainfall intensity produced on a rainfall intensity detection device. This research consists of several stages including the stages of study of literature, the design of research tools and components, the design of systems, the manufacture or assembly of tools, the testing of all components, programs and screen recordings and image capture tests. The research has successfully designed a camera-based rainfall intensity measuring instrument development has worked well and the design model of the development of rainfall intensity measurement tool that has been made in this study is that when water flows through the shower there will be rainfall. The process of rainfall will be captured and recorded by the esp32-cam microkntroler which is accessed through a computer device. Experiments carried out in the study as many as ten times the experiment, with a span of 60 seconds per experiment and the addition of rainfall every minute, the data is processed through Python software in the form of a histogram (Grayscale), which will be analyzed by the fourier transform analysis method.
