Public Lab is a community where you can learn how to investigate environmental concerns. Using inexpensive DIY techniques, we seek to change how people see the world in environmental, social, and political terms. Join now »

   




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.
