Hi everyone 👋

I’m running into an issue while trying to install and use the Adafruit DHT11 library on my Raspberry Pi 4 Model B. My system is running Debian Bookworm (32-bit) — I also tried with Debian Trixie (32-bit), but the same problem occurs.

Whenever I run the installation or try to import the library, it either fails to build or shows errors related to the setup process. I’ve already tried reinstalling dependencies, checking pip3 and Python versions, and ensuring all system packages are up to date, but the problem persists.

System Setup:

Raspberry Pi Model: 4 Model B

OS: Debian Bookworm 32-bit (also tested Trixie 32-bit)

Sensor: DHT11

Python Version: python3 --version → (please fill yours here)

Installation Command Used:

pip3 install Adafruit_DHT


Error Message:
(Paste your full error output here)

Has anyone managed to get the Adafruit_DHT library working successfully on Debian Bookworm 32-bit for Raspberry Pi 4?
If so, could you please share the steps or any alternative libraries that worked?

Any suggestions or guidance would be greatly appreciated 🙏

Thanks,
