Non-Fungible Tokens (NFTs) Explained
We want you to enter the world of non fungible tokens! A new type of blockchain based asset is taking some of the well established markets by storm. Find out why and what is our stake in it.
Smart Sensor is a multi-sensor for room automation. We developed the firmware for our client, the leading European building automation solution provider. The main goal of the Smart Sensor is to monitor the room environment and workspace quality in offices, and to do that, we had to link together the outputs of multiple sensors tracking air quality, lightness, presence, noise, etc. Sensors communicate with each other via Bluetooth Mesh while one of the sensors publishes data over MQTT to the rest of the system. We also provided the solution for commissioning Smart Sensors using the in-house Bluetooth mobile application, while the in-house dashboard tool is used for monitoring the outputs, configuring the inputs, and updating the firmware of the sensors.
Lavsa is a decentralized storage solution for smart building management, developed using IoT and Blockchain technology. Our solution is taking in a stream of data and then replicating that data to every node in our private blockchain network. Afterwards, the data set is hashed and the hash is published on the public blockchain. By using blockchain as an additional layer of security, we are improving integrity and immutability. This is a step up from the traditional database model because, in Lavsa, every piece of data is signed by the sensor and distributed across several nodes, making it impossible to change or fake the data.
In collaboration with our client, we developed a complete solution for monitoring the integrity of the building automation stations. Building automation stations control critical systems of a building, such as heating, ventilation, air conditioning, lighting, etc. Because of that, it is crucial to protect the integrity of such devices to ensure a secure and safe building automation environment. Our solution adds an additional layer of cybersecurity by putting a stronger focus on cryptography.
