Meetkoppel - Opening and welcome

Welcome-address, introducing ourselves and sorting out technical hiccups.

hackathon: Meet je Stad - Meet je Stad meets Home Assistant (combined with Using old stations for monitoring building temperature)

work session to hook up your Meet je Stad sensor to the open source smart devices platform home assistant. Bring your own raspberry pies and smart devices and get started!

hackathon: Diana Wildschut - can we measure biodiversity?

I would like to measure biodiversity in gardens or on green roofs. That could be insects, could be plant diversity, birds, you name it.
How can we automise the measurement of biodiversity? Let's just get started on a simple test and make plans for something more sound.

lecture: Paul Brouwer - Monitoring grasslands with Meet Je Stad Hardware

Last year we tested the Meet Je Stad Hardware (V2) to measure soil moisture in grassland soils. In this presentation I will show the initial results of this measuring campaign, including performance of the Meet Je Stad Hardware, soil moisture sensors and first tests using the Sensirion SCD30 CO2 sensor for field measurements.

hackathon: Meet Je Stad Amersfoort - Meet je Stad meets Home Assistent: Using old stations for monitoring building temperature

Heating a big building like the new WAR is environmentally and economically, costly. To save energy for heating we can take insulation measures or use a local heating strategy: heat only where you are.

To make better informed choices on which approach to take, we want to monitor building temperature.
In this Hackaton we will re-purpose old Meet Je Stad stations, that have been permanently removed from their location, as temperature sensors. We are going to connect these sensors to a new TTN application and send data to a database.
And while we're at it, let's see if we can connect them to Home Assistent!

demonstration: Cooperatief Meten Natuurlijk U.A. - 1 + 1 = 3 : The added value of mixing existing Biodiversity-data with other open data

A live, interactive data-analysis session where we explore the value of existing open Biodiversity data.

Last year we used the "wisdom of the Koppelting-crowd" to find out if it would be interesting to start a new project that makes existing bio-diversity data more accessible to the public. This year we fetched some observation-data from "waarneming.nl", mixed it with geoshape data from the CBS (municipality, district, neighborhood) and indexed that into an open source search-index (ElasticSearch). This allows us to query the data in different ways.

In this interactive demo we want explore the value of this "enriched" data, and create some visualizations based on questions from the audience.

lecture: Teus Hagen - Air quality measurements: applied citizen wisdom unwisely ignored

A sad real example how a local government is unable to apply citizen science in a rural region. Underwriting the national Clean Air Agreement implies an implementation plan by March 2022 and actions defined in July 2023 (Environmental and Planning Act). Explained with two of the many examples - closed LML station Hoogheide (costs >100K €) and 'Grenzeloos Meten' regional DIY sensor project (budgeted for >400K €) - is how to omit to know what you know by local air quality measurements.

lecture: Jasper Sikken - Solar energy harvesting for IoT

A quick course in solar energy harvesting. Often IoT products use expensive solar energy harvesting chips, however if your application sometimes sees outdoor light a more economic choice can be made. I also want to discuss Lithium Ion Capacitors versus Lithium Ion Batteries. And I will show an efficient and cheap solar harvesting designed for Lithium Ion Capacitor.

workshop: Coöperatief Meten Natuurlijk - Working towards uniform (real-time) data-sharing?

We believe that sharing (data) is a way to connect and build our communities. Data can be shared in many ways (formats), and the value of data increases when it is more accessible an reusable.

This session is intended as a first step to find out if we can (and want to) interconnect our initiatives on a (real-time) data-level.

In this interactive discussion we want to explore and share how the different initiatives measure, enrich, store and share their data.

Like:
* What data-formatting do you use for transport/ingest/storage/analysis?
* How do you share a temperature measurement? Binary? T, temp, temperature?
* Does your data contain meta-data (sensor/device/environment)
* Downloadable data vs real-time data
* How do you work with time-stamping? (at measurement, at ingest)

Do you think we should be working towards a uniform data interchange format?

lecture: Frans Kets (LV2 - Lucht Voor Leidschendam-Voorburg) - More fireworks, less pollution?

Although more fireworks were fired this year than ever before, pollution as measured was low. Comparisons over years are far from trivial, given differences in apparatus and weather conditions. Obvious questions arise around calibration of apparatus, source strength and distribution of the pollution.
We have used several (simplistic) approaches to derive the relation between emission and measurement for some 40 stations in Leidschendam-Voorburg and one RIVM station in The Hague over the years.
The effectiveness of the dissipation seems to be a mayor factor next to measurement quality.
Irrespective of the pollution being dissipated on new years eve, it is quite certain that the particulate matter at the end of the day will land on the earth surface, and will cause pollution of water and soil.

lecture: Joost Wesseling - The best data are fake data ;-)

When testing environmental models, it is important to be able to compare model results to actual real values. Sometimes this is not possible. In that case the creation and use of artificial, synthetic data can be a useful alternative. The synthetic data must sufficiently resemble the real data it is supposed to replace.

Work in progress on the creation and use of synthetic data from networks of low-cost PM2.5 sensors will be presented.

lecture: Ketil Moland Olsen - Sensors, data, and storytelling - How IoT can be used in journalism

Sensors are everywhere – in our offices, homes, jeans pockets and trash cans. And they play a crucial role in developing smart cities, more intelligent homes and sustainable societies. But did you know that sensor data is also helpful when important stories are to be told?

In this presentation, we take a closer look at how we can use the Internet of Things as a tool for journalism – through so-called Sensor Journalism or Journalism of Things. We will hear the story of how the extinguishing of a large and unpredictable fire was documented more precisely with the help of telemetric air traffic data and how we can reveal traffic incidents automatically through machine vision in the future.

Ketil Moland Olsen has 20 years of experience in the media and technology industry. He currently works as a project manager in NCE Media/Media City Bergen, an innovation cluster with close to a hundred member companies throughout Norway. He is also involved in the Bergen branch of the Measure Your City project.

lecture: WiLa Leipzig, Florian Fahr & Patrick Schonfeld - The X-Hab, a nesting aid with a scale

We present our current project in the making, the X-Hab. And shall work like a sense-box for ecological biotic data. Therefore we are working on a birdhouse with scale, camera and sensory combined with a database and a construction manual for everyone to replicate.

lecture: Will Loermans (Ontdekstation013) & Miriam van den Beemt (de Bibliotheek Midden-Brabant) - A supporting platform for the community

Students of Fontys ICT (university of applied science) are working on a community platform for Meetjestad Tilburg. On this platform, people who have built a measurement station will be able to connect their station and share the data. There are different ways to see the data and the relation between the different measurements. Also, the platform gives us the opportunity to monitor the stations automatically and keep people involved with Meetjestad after the solder workshop. We present the current status of the project and share our next steps.

lecture: Gidske Andersen and Knut Krzywinski - Setting up MjS stations in a remote area - adaptations, challenges and experiences

In October 2022 we established a network of 11 MjS stations in Erkowit, Red Sea Hills, Sudan. The stations are recording temperature and humidity, two important factors for understanding the ongoing recovery of the endangered Dragon blood tree. In this talk we will share our experiences in setting up this system in an area with limited infrastructure. We will also show some of the first results and discuss the challenges we have faced.

other: Monike Van Duren - Meer Meet je stad

Tweegesprek tussen De WAR (oprichters van Meet je Stad) en Monike van Duren ( teamleider wonen en milieu van de gemeente Amersfoort), over hoe Meet je stad kan worden doorontwikkeld tot instrument van beleidsontwikkeling en innovatie.

lecture: Bertrik Sikken - Visualising open energy data

I would like to present what kind of open data is available around energy, in particular electricity and natural gas. For example, open APIs that give information about dynamic energy prices, but also dynamic information about how electricity in the netherlands is generated.

I will demonstrate this using a LED ring light that shows the dutch electrical energy mix as a kind of pie chart, with each generation source (solar, wind, fossil, nuclear, waste, etc) as a colour, updating every 15 minutes.

workshop: Waag Futurelab | Imme Ruarus - Hollandse Luchten: Methods for citizen science research

During this workshop we will share the lessons we have learned over the years in Hollandse Luchten (a citizen measurement platform for air quality) for starting a citizen science research. In particular we will share knowledge and tools on how you make a collective measurement plan. Your reflections and ideas are very welcome! In the second part of the workshop we discuss what is needed for successful citizen science data analysis: what are your experiences so far, what do you need, what works and what doesn't?

lecture: Stefan Lehner - How to improve production of for MJS kits

We want to improve our actual drilling installations to fasten the production of our MJS devices by developing polyvalent machines which we can use also for the productions of other objects. The basic purpose is to build micro-fabrications lines in the WAR.
