Hi.
You need to change the code to use those specific pins for you board.
You can check our I2C tutorial to learn how to do that: https://randomnerdtutorials.com/esp32-i2c-communication-arduino-ide/#3
Regards,
Sara

just found your answer to a previous question and your guide to fixing it and the IC2 scanner – even though the pinout on the Waveshare shows 6&7 (https://www.waveshare.com/wiki/ESP32-C6-DEV-KIT-N8) it was still pins 21&22. still need to test the CYD though

I can connect a 1 wire(DS18B20) fine

The BMP works fine on a Nano

Your problem, you have a lot of problems, Chinese products are very good.

The module can run with 3.3V or 5V.

Hi.
You have to adjust the sea level pressure at your location on the following variable:
#define SEALEVELPRESSURE_HPA (1013.25)

Sara

I have one issue with this project, the altitude doesn’t display correct, i know the netherlands for the most part is under sealevel but -187Meters is a bit much. What can I do to change this.
