LoRa Based Wireless Weather Station

Abstract

This research creates a weather station prototype using LoRa wireless technology. The internet of things (IoT) system is supported by LoRa, a wireless networking technology. This technology is an alternative to existing wireless communication modules such as GSM modules, Wi-Fi modules, and Bluetooth modules (BLE). The LoRa network is used to extend the range of wireless cells, allowing them to reach distances of up to 10 kilometers while consuming very little power. End devices can be connected to hundreds of nodes using a single LoRa network cell. Temperature, humidity, air pressure, rain detection, and wind speed are among the weather data that are monitored. The Atmega 328 microcontroller, DHT11 sensor, BH1750, rain sensor, BMP180 sensor, ESP32, LoRa module, solar panel, and web application are all included in the prototype. The number of end device nodes created in one cell is three. As a consequence, the system will be able to work correctly. With several types of sensors attached, this system has the potential to be applied in both urban and rural locations. Data collected from the sensors are then stored into the Firebase real-time database, a cloud-hosted database, and a mobile application is developed using MIT App Inventor to show the real-time weather conditions of a particular region in an android mobile phone.
