LoRaWAN Demo

A LoRaWAN-based Internet of Things (IoT) demo is created at the Advanced Networks Research Group (ANRG), University of Liverpool. This is completed by Mr. Wenpeng Fan as his final year project during 2018 - 2019.

Overview

A light sensing and control IoT system is created as a case study. The LoRa end device is consisted of FiPy (with LoRa function) and Pysense (expansion board) with light sensors. A LoRa end device A will sense the light and transmit it to the application server. When the luminous intensity is smaller than a threshold, it will send a control signal to the LoRa end device B and turn its LED to green, emulating a control signal to a switch.

Key Features

• Regular uplink transmission
• Manual downlink transmission (confirmed or unconfirmed)
• Automatic downlink transmission (determined by the threshold)

Setup

• Hardware
  • End device: FiPy + Pysense
  • Gateway: Raspberry Pi + RAK831, an instruction can be found at https://www.thethingsnetwork.org/docs/gateways/rak831/
• Software
  • TTN to host the gateway and applications
  • Python SDK
  • Micropython for the FiPy
