Ask a question
The easiest way to start with Public Lab community is to ask a question.
See questions and ask your own here:
I. The Problem
Communities lack access to the tools and techniques needed to participate in decisions being made about their communities, especially when facing environmental hazards.
II. The Collaboration
We are an open network of community organizers, educators, technologists and researchers working to create low cost solutions for monitoring air, water and land.
Discover, collaborate on, and contribute to locally important matters with the support of a global community.
III. The Solution
Join us today, as we work together to build and inspire a community of DIY activists and explorers using simple tools to build a growing body of data about our local environments.
