Development of wind monitoring systems with LoRA technology

Abstract

The purpose of this research is to design and build a wind monitoring system with LoRA (Low Range) technology. This system can observe the value of wind speed, air temperature, and humidity. All of these data must be processed in order to obtain information on the current state of the air. Existing information can be used as a reference for decision making or as a sign of a threat. In this monitoring system, the observation of air conditions uses wireless LoRa (Long Range) technology as a data transmission tool. In this experiment, two LoRa nodes are used and one Lora Gateway is used. There are two sensors used in this case, namely anemometer and BME280. Sensors contained in the LoRa node take data on wind speed, air temperature, and humidity. The LoRa node sends all the data to the LoRa Gateway. LoRa gateway connected by wifi will forward to the server (The Things Network and Firebase). The test results from this study show that the average time for sending LoRa node data to being sent to firebase is 0.25 seconds. LoRA devices with a 3 cm long antenna can communicate at a maximum distance of 400 m.
