This sensor was published in Scientific Reports! Read an Open-source, low-cost, in-situ turbidity sensor for river network monitoring here.
This repo is dedicated to the open-source turbidity sensor. More info can be found here:
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
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.
For questions, please email me at droujko@ifu.baug.ethz.ch or @rivertechjess on Twitter 🐦
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)
