Low Cost IoT Based Weather Station for Real-Time Monitoring

The Internet of Things (IoT) is a modern innovation in today's world of the Internet, establishing an interconnection between devices and individuals and exchanging information through a shared platform. This paper proposes a low-cost water station based on IoT that can provide critical water information in real time, such as wind speeds and direction, temperature, humidity, and amount of rainfall. The use of low-cost but reliable controllers from Node MCU and Arduino UNO makes it accessible for a wide range of clients. The availability of information on a ThingSpeak web server guarantees the authorized person's access to data from anywhere in the world. A 3 cups anemometer and wind vane are used for wind speed detection and wind direction measurement, respectively. The DHT22 digital temperature and humidity sensor are used for the measurement of temperature and humidity. A custom acrylic glass rain gauge is designed for rainfall measurement. With the aid of a circuit, all weather data was de-bounced, and this de-bounced data was uploaded directly to the ThingSpeak server. This proposed design will solve the problem of the unavailability of weather information at different locations. Low-cost design, while ensuring reliable and accurate measurements, will encourage the use of the proposed design in many research and educational institutions as well.
