GOSH Community Call: Environmental Sensors

Dear GOSH Community,

We are excited to announce our upcoming GOSH Community Call on open source environmental sensors - and our first call in Spanish!* We are co-organizing this call with CoSensores, a group of professors, students, and researchers developing free scientific technologies for environmental monitoring alongside communities immersed in environmental conflicts. The call will feature presenters from the University of Texas at Austin, Laboratorio Agroecológico in Argentina, and more!

The call will happen on April 9th at 12 pm UTC - Register here!

*Note: The call will be held in Spanish, but we will have English interpreters available.

Dear GOSH Community,

We are excited to announce the speakers for our upcoming GOSH Community Call on Environmental Sensors, happening on April 9th at 12 pm UTC. We’ve got a fantastic lineup of presenters from CoSensores, Caminos de Agua, Hacking Ecology, Laboratorio Agroecológico, and the University of Texas at Austin. Find out more about the speakers below!

Register for the call here.

Fernando “Nano” Castro – Laboratorio Agroecológico Abierto/reGOSH

Professor and researcher at the Faculty of Agricultural Sciences (UN Cuyo). Nano works at the interface between scientific/technological communities and local communities that need to improve their production practices or monitor their environment. He has facilitated numerous open scientific tools workshops in Chile and Argentina. He is currently working alongside the Latin American community reGOSH to develop and establish an Open Agroecological Laboratory.

Juan Pedro Maestre – University of Texas at Austin

Dr. Maestre (Juan P. M.) is an environmental scientist and Research Scientist at the University of Texas at Austin, dedicated to the research of air (and water) quality. This presentation will focus on an open source device, the Beacon, used to measure air quality.

Aaron Krupp – Caminos de Agua

Caminos de Agua is a non-profit organization registered in the U.S., as well as a civil association in Mexico (A.C.). with a mission to improve human health and community well-being through adequate and affordable access to clean water We work collaboratively with local communities, leading research institutions, and other diverse stakeholders to innovate and implement water solutions that result in adequate access to clean and safe drinking water sources in the region where we work: the northern part of the state of Guanajuato, in central Mexico. Aaron Krupp (former coordinator of research and technology at Caminos de Agua) will present a project that they have been working on since 2018 in collaboration with IO Rodeo and a group of researchers at the University of Liverpool to develop an open source and low-cost system for the measurement of arsenic in water samples. The presentation will focus on the achievements to date (system testing, software, and hardware development, collaborations with various student groups) and look to the future (an accessible guide on how to make your own arsenic measurement, maybe a measurement kit!).

Saulo Jacques – Hacking Ecology

Hacking Ecology is a group of ecologists, technologists, and environmental advocates who build high-precision, fair-priced systems for environmental monitoring. Nayad is an accessible and flexible open hardware for environmental monitoring integrated into an automated auditing platform that verifies the veracity and quality of the data collected. Social media profiles: Twitter, Mastodon, Instagram, Gitlab

Lara Jatar and Kevin Poveda Ducón – Grupo de Sensores Comunitarios (CoSensores)

CoSensores is a group of professors, researchers, and students from different national universities in Argentina. Since 2013, they have been working on the development and fine-tuning of freely accessible tools and technologies for the monitoring of environmental variables, mainly linked to water quality, through participatory survey strategies with communities that are immersed in environmental conflicts. The group has created a microalgae-based bioassay adapted to be implemented in the field with organized communities immersed in environmental conflicts, mainly related to water contamination by agrochemicals as a result of the expansion of the agro-industrial frontier, which was developed and fine-tuned. More recently, within the framework of the work of doctoral fellows and researchers from the CoSensores group, in connection with the Laboratory of Integrated Processes of Environmental Analysis and Remediation and the PhD in Environmental Sciences of the Institute of Environmental Research and Engineering (IIIA) of the National University of San Martín (UNSAM), the development and validation in the laboratory and in the field of open-source scientific tools to measure variables of interest has been deepened such as conductivity, pH, dissolved oxygen, turbidity and various nutrients (nitrate, phosphate, etc.) using colorimetric and nephelometric techniques with a low-cost colorimeter.

Hi everyone,

This message is a reminder that the next GOSH Community Call about open source environmental sensors will take place on April 9th at 12 pm UTC.

Hello everyone,

Thank you to the participants and presenters who joined the recent GOSH community call on open environmental sensors. We had five presentations, more than thirty participants, and it was the first call in Spanish with interpreters!

You can read the notes from the meeting here: https://pad.publiclab.org/p/GOSHcommunitycalls

Unfortunately, I couldn’t record the presentations, however, I am sharing the presentations here: https://drive.google.com/drive/u/1/folders/1Yu9HQDUri-eJuUSh7e-SiTKSLdEEqWyw

GOSH Forum category about open environmental sensors
We created a new category to continue sharing the work carried out by various groups in the field of environmental sensors, as well as experiences, doubts, and proposals. We hope to create a space to weave relationships and strengthen the network in this field: https://forum.openhardware.science/c/communities/sensores-ambientales-abiertos/79

See you at the next call!

Thanks for organizing this call with all those interesting regional actors in the field!

I mentioned briefly in the chat, that I will be traveling for a research and networking trip to Argentina, landing in Buenos Aires on the 23rd of April. I would be super happy to meet some GOSHers and related people in-person during the visit!

We already planning a meeting with @laola on the first days of my arrival. More info about place and time soon.

Later I will be around with @nanocastro and @Fernan in Mendoza for sharing our recent experiences with various open science hardware enthusiasts and finally spend some time together after working years online on the CO2 chambers for soil analysis, and other stuffs.


So nice to meet already many GOSHers from the region in-person!
@Laraja @OctavioDuarte @laola and more. Thanks for the asado!

We had nice discussions on why those in-person hang-outs matter, and how so many of our global GOSH networks are flourishing both regionally and online.

I will update my personal research notes here on the hackteria wiki:

Next meeting in Mendoza with @nanocastro and @ffederici coming up in a few days. Good timing to refelct on earlier GOSH gatherings… to prepare to our next one in Indonesia, approximately in 1 year +.
