Lab Technology, Hardware & Services

The lab maintains technologies, hardware and services that make up the infrastructure for working with data - for data science in the widest sense of the term, from creation of data over transport to storage, analysis and applications.

Sensors

sensors image

You are likely to find any type of sensor you can imagine in our sensor library. If we do not have it yet, we can add it.

Our focus areas include - air quality, indoor and outdoor (NOx, COx, O3, vapors, alcohol, …) - water chemistry and properties (temperature, pH, dissolved oxygen, conductivity, ammonia, nitrite, and others) - water meters - acoustics, audio, vibrational sensing - sensors relevant for agricultural and environmental research

IoT networks

IoT image

We have boards and modules for (and experience in) LoRa(WAN), Sigfox, zigbee, LTE, 802.15.4, WiFi, BLE and can add all networks of interest for IoT applications.

In additon ot physical items, we maintain the invisible part of IoT, the networks: we operate one of the busiest danish gateways on The Things Network, reaching far into Sweden and all the way to Germany on a good day, plus a number of other gateways, in projects all over Denmark and beyond.

We participate in beta testing satellite LoRaWAN networks.

Here s an introduction to some of this, as presented at the Copenhagen Techfestival 2018:

Resources for data science & machine learning

We maintain a wide variety of infrastructure and services for data sceince in the widest sense of the term, both as physical infrastructure and within the virtual environment of the IT University.

  • GPU boards & clusters
  • Ambari / Hadoop / Spark environment
  • Grafana
  • Databases, relational and timeseries DBs

Currently (Oct 2020), the DASYA Lab is managing the ITU HPC Cluster, http://hpc.itu.dk (internal network only).

PITLab Aquarium

aquarium image

The PITLab Aquarium was a small in-lab water tank, equipped with the following sensors: – pH – DO (Dissolved Oxygen) – Conductivity – Reduction Potential – Temperature (all sensors by Atlas Scientific, http://atlas-scientific.com/ ) The aquarium was used in various research and education activities, and while it is no longer active, all its components are still there.
