Prototype weather station uses LoRa wireless connectivity infrastructure

Abstract

This study develops a prototype of a weather station with LoRa wireless infrastructure. LoRa is a wireless connectivity technology supporting the internet of things (IoT) system. This technology is an alternative to other wireless connectivity modules that have already been popular such as GSM modules, Wifi Modules and Bluetooth (BLE). The use of the LoRa network serves to increase the range of wireless cells that can reach distances of up to 5 kilometers while still having low power consumption. One LoRa network cell can connect end devices to hundreds of nodes. Weather parameters measured include temperature, humidity, air pressure, rain detection, and wind speed. The prototype consists of Arduino UNO, DHT11 sensor, raindrop sensor, anemometer sensor, BMP180 sensor, LoRa shield, LoRa Gateway, and ThingSpeak web application. While the number of end device nodes built is 3 nodes in one cell. As a result, the system can function properly. This system has the potential to be implemented in urban and rural areas with various types of sensors connected. Between cells can be managed to form a Low Power-Wide Area Network as a wider sensor network.
