Public Lab is an open community which collaboratively develops accessible, open source, Do-It-Yourself technologies for investigating local environmental health and justice issues.
Want to talk about soil contamination? Join us on any Tuesday Open Call in February and March. We'll kick-off a research area review on this topic on Feb. 2! Click here for details on how to join!
Water conductivity monitoring
**Conductivity** is a measure of a solution's ability to conduct electricity, as measured in Siemens per meter (S/m). (lead image by @ddileona)
This page is under development, please add background info:
* Info about regulations
* Info about ecological or human health impacts
* Advocacy leverage points
* Constraints we're working within: cost, complexity, sensitivity, time
Also see resources on this page: https://publiclab.org/wiki/conductivity_sensing
Here's a list of different conductivity sensors and measurement systems. Also see below for some Do-It-Yourself approaches to measuring conductivity, and [this page](https://publiclab.org/wiki/conductivity_sensing) for more information.
