Rainfall Monitoring System Using Tipping Bucket Rain Sensor Based on Internet of Things Nodemcu ESP8266

Introduction

Rainfall is a crucial parameter that plays a significant role in determining the impact of rain on an area. Measuring rainfall is essential to understand the amount of rainwater that falls to the ground per unit area. Specifically, this rainfall measurement shows the thickness or height of the rainwater surface that covers an area on the surface of the earth. One of the most common systems used to measure rainfall is the tipping bucket rain gauge. This tool is designed to record the amount of rainfall that falls in a certain period. In this article, we will discuss the design and implementation of a rainfall monitoring system using a tipping bucket rain sensor based on Internet of Things (IoT) technology with Nodemcu ESP8266.

Tipping Bucket Rain Gauge

Rainfall measurement using a tipping bucket works in a simple but effective way. This tool consists of a funnel that captures rainwater and two containers that are installed in the opposite manner. When rainwater enters the funnel, the funnel will be filled and when it reaches a certain capacity, one of the containers will "fall" (tipping) and drain water to another container. With every time the container falls, this master records the amount of rainfall that has occurred. There are various sizes of funnels for measurement, and in this study, a resolution of 0.7 mm is used. The tipping bucket rain gauge is a reliable and accurate method for measuring rainfall, making it an ideal choice for various applications.

Use of Hall Effect Sensor

To increase measurement accuracy, this system is also equipped with a Hall effect sensor mounted at the bottom of the funnel tipping bucket. This sensor serves to detect magnetic movements attached to the bucket mechanism when it rains. Every time the bucket is reversed, the sensor will send a signal to the microcontroller. The microcontroller will then process this data and display the amount of rainfall recorded on the LCD screen. The Hall effect sensor plays a crucial role in enhancing the accuracy of the rainfall measurement system. By detecting the magnetic movements of the bucket, the sensor ensures that the system accurately records the amount of rainfall.

Application of Internet of Things (IoT)

The advantage of this system lies in the integration of Internet of Things (IoT) technology with the use of the Nodemcu ESP8266 module. By using nodemcu, the rainfall data measured is not only displayed locally on the LCD, but can also be sent to a server or cloud-based application. This allows users to monitor rainfall in real-time from a distance using smartphones or other devices that are connected to the internet. This data can be accessed anytime and anywhere, providing convenience in making decisions related to weather conditions. The IoT technology enables the rainfall monitoring system to be more efficient, reliable, and accessible.
