Development of a Weather Station with Water Level and Waterflow Detection using Arduino

Abstract

Weather data monitoring is important due to the drastic changes of weather around the world in recent years. Weather-related parameters are commonly measured using weather stations. Low-cost Arduino based weather station is suitable for public use to monitor local weather conditions in the vicinity of their residential area. This will enable quick response in natural disaster caused by the weather. In this work, the integration of water level and waterflow rate detection to the weather station allows hydrological data measurement in addition to the meteorological data. This capability makes the weather station suitable for further expansion into a wireless sensor network for flood monitoring and prediction. This weather station was developed using NodeMCU ESP32 microcontroller, ultrasonic sensor, BMP280 sensor, rain sensor and waterflow sensor. The remote data monitoring capability was realized using Blynk IoT platform. A prototype of this weather station was developed and tested in a simulated environment. Results show that this weather station is able to provide good measurement of meteorological and hydrological data.

Wireless Water Level Detection System

“…Water level and flow rates have been simultaneously measured for hydrological data measurements (Mamat et al, 2022) and flood early warning systems (Yoeseph et al, 2022). A novel approach for determining water discharge using water flow velocity, sectional area width, and sectional average depth was proposed by Prakash et al, (2022).…”
