How can I see the (binomial) value of the AM2302 temperature sensor on the display?

Hi,

I've create a DHT11 Sensor Block with this documentation. Create DHT11 Block

But when I click on "Monitor and Tune", I have an error message, see in DHT11_model...txt.

Thanks for your help.

Hello,

You may try troubleshooting steps such as:

• Use the exact example flow for DHT11 (IO Device Builder) and include Adafruit DHT + Unified Sensor libraries as shown Create DHT11 Sensor Block to Measure Relative Humidity and Temperature Using IO Device Builder App - MATLAB & Simulink
• Add the source file that implements those functions: In IO Device Builder Source files, include the .cpp/.c that defines setupFunctionDHT11 and stepFunctionDHT11 (from the example or your driver). Re‑generate the block. How to Build Custom Sensor Blocks for Arduino in Simulink - MATLAB & Simulink
• Clean rebuild: Delete DHT11_model_ert_rtw/ (or run a clean build) and try Monitor & Tune again. Tune and Monitor Model Running on Hardware - MATLAB & Simulink

Hope this helps.

I have done this manipulation, but I have the same problem. In the attachments, you will find my files for the DHT11 and a screenshot of my screen in Matlab. I'm not sure about the last step of your explanation. Thanks
