Q-Sphere, London, [IoT]
Q-Sphere Company from London is specialized in multiple tech verticals: Fintech, IoT and eLearning. In their IoT portfolio, among other products, Q-Sphere is developing proprietary Central Controller (CC) device that is used for sensor data acquisition and communication of the data to the Cloud database.

In this project, Gray Cell developed firmware for the Central Controller to enable advanced Network Routing Protocol which will enable more stable and synchronized operation of multiple CCs fleets in one large system (e.g. in a big business building with more than 500 desks or in a large hotel). Also, a distributed ledger database is developed and used to store data from all CCs in the system to ensure that there is no data loss during emergency operation.

Technology used: Python for Proof of Concept and C++ for production software
