Maria 01 features, APIs, and specification

Here is a collected list of available Maria 01 campus features, sensors and APIs that are available with a dedicated token.

Indoor environmental quality

Indoor environment and air quality values can be measured in various ways at Maria 01:

CO2 & CO2 history

CO2 is an indoor environmental quality API that enables reading E-CO2 data. The current data is best for tracking changes rather than exact CO2 values. Link to CO2 API specification and CO2 history API.

Data frequency: 10 seconds
Sensor location: Maria 01 meeting rooms
Sensor model: Nordic Thingy:52

Humidity & humidity history

Humidity API enables reading humidity values. Link to humidity API and humidity history API.

Data frequency: currently around 5 minutes, will be lowered due to battery consumption
Sensor location: Maria 01 open working areas and their surroundings
Sensor model: Treon node

Atmospheric pressure

Atmospheric pressure data can be read in mbar values. Link to air pressure API and air pressure history API.

Data frequency: currently around 5 minutes, will be lowered due to battery consumption
Sensor location: Maria 01 open working areas and their surroundings
Sensor model: Treon node

Temperature

Temperature API enables reading indoor temperatures. Link to temperature API, temperature per area, and temperature history API.

Data frequency: currently around 5 minutes, will be lowered due to battery consumption
Sensor location: Maria 01 open working areas and their surroundings
Sensor model: Treon node

Ambient light

The amount of ambient light is measured in lux. Link to lux API and lux history API.

Data frequency: currently around 5 minutes, will be lowered due to battery consumption
Sensor location: Maria 01 open working areas and their surroundings
Sensor model: Treon node

Sound & sound history

Sound API enables reading noise data as an RMS value. Link to sound API and sound history API.

Data frequency: currently around 5 minutes, will be lowered due to battery consumption
Sensor location: Maria 01 open working areas and their surroundings
Sensor model: Treon node

Calmness Index

Calmness Index (CI) is a metric assessing how calm and peaceful a space will be during a given time interval. CI tells the probability that there will be disturbance in the given space at any given moment during the time interval. So if the CI is 0.1 for the next hour in a coworking space, then there is a 10% chance of disturbing activity for that hour, which means 6 minutes of disturbance on average.
The CI can be utilized by other applications to provide a more simple and possibly user friendly presentation of calmness by mapping the CI to a category, e.g. calm, active, or noisy.

Calmness API provides information about the current calmness and the predicted calmness in the near future. Link to calmness API coming soon.

Data frequency: situation and predictions available as requested. This API relies on other data sources, especially sound data, so sound data frequency affects how often the CalmCast model gets new information about the space.
Sensor location: Maria 01 open working areas and their surroundings
Sensor model: None, CalmCast is an ML model which enriches the existing data provided by other APIs.

DAC + HAIP

Nokia Digital Automation Cloud (DAC) and High Accuracy Indoor Positioning (HAIP) are available at Maria 01 test site in KEKO lab, Read more.

Location: KEKO lab in building 3

Floorplan

Maria 01 floorplans are provided through floorplan API. Note that some of Maria 01 buildings are over 100 years old and CAD files are based on hand drawings.

Occupancy & occupancy history

Presence API enables to read what meeting rooms and phone booths are currently in use. Sensors are PIR sensors. Link to occupancy API specification and occupancy_history API


Sensor location: Maria 01 meeting rooms and phone booths
Sensor model: Promistel wirepas PIR module (manufacturer’s datasheet)

Mesh network

Wirepas mesh network connects existing sensors to KEPPI/KEKO platform, but it can also be used as a backbone for connecting new sensors online. Mesh network can also be used for tracking. Note that connected Wirepas nodes need a security key and wirepas 5.X version installed, contact us for more information. Read more here.

Sensor location: Maria 01 campus area

Philips hue lights

Philips hue lights are available in Maria 01 main building (building 1) at primary routes and they can be used, for example, for navigation and informing users. The lights are not connected to KEPPI/KEKO Platform.

Location: Building 1 main routes
Model: Philips hue lights
