Introduction

This repo is dedicated to the open-source turbidity sensor. More info can be found here:

• https://rivertechlabs.org/
• https://hyd.ifu.ethz.ch/research/riparian/susp-sed-sense.html

This repo contains several items to build the current prototype of the open-source turbidity sensor including:

• The code needed to upload to the ESP32
• CAD files
• Hookup schematics

Code

Before you begin, you need the ESP-IDF installed on your computer. Please visit the Espressif website for more information on installation.

The current code takes 100 frequency measurements and enters deep-sleep for 1min, this can of course be changed. Also, the code isn't beautiful and I apologize but it will get better with time.

Hookup schematics

Prototype 1.0

This repo also contains the CAD files for prototype 1.0 of the turbidity sensor (you can use this to 3D print the device in a school project)
