<div class="markdown_content"><p>Hey guys,<br/> i connected my MCP3008 DAC to the pi and i can now read analogue signals. I wanted to ask you if you have experience with using a temperature-humidity sensor?<br/> I thought of the DHT22:<br/> <a class="" href="http://www.exp-tech.de/dht22-temperature-humidity-sensor-extras?gclid=CjwKEAjw0-epBRDOp7f7lOG0zl4SJABxJg9qbkMjlNuq4pGrY_iR5AUwUocpcZR3gImUsnPKYPXgNxoC4mTw_wcB" rel="nofollow">http://www.exp-tech.de/dht22-temperatur ... oC4mTw_wcB</a></p> <p>Could i just connect this one to the MCP3008? And how can i read the two different signals with one data connection then? <br/> I found some instructions with python(<a class="" href="https://learn.adafruit.com/dht" rel="nofollow">https://learn.adafruit.com/dht</a>), but im not that familiar with codesys yet so i dont know how i can 'translate' that ^^</p></div>
