This project was made as part of a discipline taken on a Computer Science Master's Degree program. The objective of this Proof of Concept was to demonstrate the usage of WIFI signals to create fingerprints and then estimate the location of the device by using machine learning algorithms.

IoT Button code written in Lua for the nodemcu firmware installed on a ESP8266 chip (ESP-01 model).

Node.js API responsible for the location feature via the KNN algorithm and the communication between the MQTT broker and the React frontend via Websockets.

It serves the build folder which was generated from the poc-iot-web project.

React project created with create-react-app to manage the creation of the radiomap of WIFI signals fingerprints and view the discovery of location by pressing the button on the device.

Node.js RethinkDB instance.

If running on c9.io it is required to start the database with the attribute bind all: rethinkdb --bind all --http-port $PORT
