DHT22 and Controllino Maxi AUTOMATION

[mat1996]

Hello everybody,

Today I make a project on a controllino maxi automation. I have an issue because I would like to use a humidity/temperature digital sensor DHT22 from adafruit.
My problem is that this sensor is digital and operate in 0-5 V and the digital input in the controllino is in 0-24V.
I was thinking that if I amplify the signal with an oeprationnal amplifier it should be working, but maybe some of you would have better Ideas?

Thanks you very mutch !

Hello mat,

You have to connect 5V things to the pinheader!
We have a tutorial on how to connect a DS18x20 sensor to our CONTROLLINO on our homepage.
The sensors are not very different.
