  1. 1. Fire detector sensor nodes using Long Range (LoRa) radio communication : Branddetektorsensorer som använder Long Range (LoRa)

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Roney Yelda; [2023]
    Keywords : ;

    Abstract : Fire can be fatal, burning homes and forests and its emissions can pollute the air. To prevent these types of catastrophes, it will be necessary to develop a sensor module capable of detecting and alerting humans by sending a signal via a network called The Things Network (TTN).
