Hello,
I have purchased the BME688 sensor on Sparkfun 19096 board. I have connected it with I2C communication protocol to esp32 pico d4 development kit and used the SV-Zanshin Arduino library on GitHub to read the sensor data. All data show as expected except the gas measurement which doesn't change value.
My questions are:
1. What does the bare value read from the sensor represent? Ohms, KOhms?
2. Can I connect the sensor to Arduino Uno with 5V supply? The Sparkfun board doesn't have voltage regulator. Will the 5V logic of Arduino uno work?
3. Why is the resistance value of the sensor not changing and the bare value read is 13007335?
Many thanks! Greatly appreciated!
