Perancangan dan Pembuatan Alat Pendeteksi Ketinggian Air Sungai Menggunakan Koneksi Internet Of Thing (IoT) Berbasis NodeMCU ESP8266

Abstract

Flood is an event which the water excess the water subsides the land. The flood streams with the normal river streams can be distinguished by looking at the level of river water stream. The Stream which transcend reservoir become signs of flooding. The water level can be measured by using the transmission process and reflection of ultrasound waves

The purpose of this experiment is designing a device that detect the water level based on IoT and NodeMCU microcontroller board attached to the input and output connected by the microcontroller. The input device of the ultrasonic sensor leds under monitoring use the blynk in Internet connection. This device works based on the main indicator and it is the water level. When the detecting indicator go beyond over limit as the limit of safety. So output device like buzzer and led will be operated automatically by microcontrollers. The rule of safety limit for ultrasonic sensor is not more than 20 cm.
