Hey guys,
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?
I thought of the DHT22: http://www.exp-tech.de/dht22-temperatur ... oC4mTw_wcB
Could i just connect this one to the MCP3008? And how can i read the two different signals with one data connection then?
I found some instructions with python(https://learn.adafruit.com/dht), but im not that familiar with codesys yet so i dont know how i can 'translate' that ^^

Hi,
connecting this to MCP3008 will not work,
a serial protocoll is needed.
An option might be to use this sensor:
