My engineering capstone project. Uses wireless LoRa transceivers to determine the precise location of a wearable device in industrial environments. Wearable device can detect falls and other dangerous conditions using onboard sensors. Publishes information over MQTT to client based GUI.

lora-rssi-localization's Introduction

locServer

Functions as both a localization node and as a server to calculate and display the location of the localized node.

Receives two types of packets: pings to calculate RSSI when used as a node, and data packets that aggregate the RSSI from all three nodes and sensor information. Sends a simple acknowledge to pings, and parses and processes data packets.

localizedNode

Sends multiple pings to all nodes and stores their RSSI values. Formats information into a delimited string and sends to raspberry pi server as a data packet.

receiveNode

Receive pings from localized node and send an acknowledge to calculate RSSI.

mqttPublisher

Sends calculated cartesian coordinates and sensor data over mqtt on the rssi topic. Intended to be received by mqttReceiver and displayed on a GUI, but could be used by anything as its just a formatted string.

mqttReceiver

Subscribes to rssi mqtt topic and waits for messages to come from raspberry pi server. Parses data string and displays on GUI.
