3nd Year Embedded Systems IOT Coursework

Group Name: Keleido

Product: Guesture Reconstruction with its Applications Using Flex and Other Sensor

The product takes input from a single flex sensor with an additional accelerometer and transmit the information via MQTT and the data format is JSON, the information is then subscribed by multiply devices to further process the information. In this repository there are a few demo in the folder src/gui, but the application is unlimited and here is just a glance of what the technology can be applied to.
