Design of Sensor Network with Long Distance Communication for application in Building Energy Management Systems

This paper presents the design of a sensor network capable of transmitting data over long distances (up to 1000 meters) achieving reliable data, with the aim of improving energy consumption efficiency in Bulding Energy Management Systems (BEMS). The processing system uses Heltec WiFi LoRa 32 v3 microcontroller, the communication protocol proposed is LoRa (Long Range) and the IoT (Internet of Things) platform to remotely view and control sensor data is Ubidots. The main contribution of this project is the design of environmental sensor node with high range of communications capabilities using LoRa 32 devices and found the right combination of the different communication factors (distance, spreading factor, bandwidth, and power). The project seeks to contribute to the field of building automation and long-distance communications allowing greater efficiency in energy consumption, reducing costs and minimizing environmental impact. Finally, communication validation is planned.
