Bme688 H2S detection

[ilcnet]

Hello
The BME688 sensor can detect H2S gas normally without calibration? Because the H2S is so dangerous and we cant use the AI software to learning the BME688 sensor to detect it.thanks

Hi Robin, im working with cumstom PCB's based on ESP32 and STM32H7 microcontrollers. I got the BME688 working, but  i have some  doubts about it.

  1. How can I extract VOS(Sulfurs) values from the raw data?

2. gas_meas_index colum, How  is  it related to gas quality, or it is just a Heater state?

I want to parse these data in real time to feed another algorithm , Hence, I appreciate , if you can give me some support to achieve that.
