<div class="markdown_content"><p>Hello,</p> <p>I want to use Raspberry Pi + Codesys as a Chemistry Controller for my pool. The Idea is to measure PH and REDOX Potential with Electrodes and control Pumps for injection of necessary chemistry.</p> <p>I found following RPI modules, which are suitable for measurements:<br/> <a class="" href="https://www.atlas-scientific.com/product_pages/circuits/ezo_orp.html" rel="nofollow">EZO ORP</a>, <a class="" href="https://www.atlas-scientific.com/product_pages/circuits/ezo_ph.html" rel="nofollow">EZO PH</a> from Atlas Scientific and <a class="" href="https://www.atlas-scientific.com/product_pages/components/tentacle-t3.html" rel="nofollow">Tentacle T3</a> to host those on RPi. The boards have I2C Interface and supplied with source code on Python.<br/> How do you think would it be possible to make the readings via Codesys? Or perhaps someone did driver already? Or is there any other alternative measurement modules available?</p></div>
