Prototipe Deteksi Hujan Berbasis Arduino Uno Menggunakan Rain Drop Sensor Module

Abstract

Indonesia's climate is mostly hot and humid, with most of the rainfall occurring, less alert to the occurrence of rain when indoors, at home and in the office. To take the necessary action when it rains, we need an alert for the problem. The purpose of this research is to make people aware about rain without realizing it, by making an Arduino-based rain alarm sensor and implementing the fourth industrial revolution in everyday life. The research method is the implementation of using an Arduino-based Raindrop Sensor which is an Arduino standard board based on the ATmega328P microcontroller. The Raindrop Sensor Module works when it rains, when it rains the buzzer vibrates, the buzzer will provide information in the form of sound. The results of the research that the sensor value is more than 500 with the green light indicator Buzzer does not make a sound then the condition is not raining or it can be interpreted as sunny weather, then the sensor value is less than 500 with the buzzer indicator then emits a sound and the red indicator light is on, it indicates it is raining.
