Great addition

Small footprint and provides all the environmental data I need.

5 FAQ

Q: Which library do you recommend?

A: We recommend the Adafruit BME680 library for Arduino and Python.

Q: What is the default I2C address?

A: The default address is 0x76, but it can be changed to 0x77 via SDO pin.

Q: Is this module 5V tolerant?

A: The sensor operates at 3.3V. Use a logic level converter for 5V MCUs.

Q: How long for gas sensor stabilization?

A: Typically 48 hours of continuous operation is recommended for accuracy.

Q: Can it measure altitude accurately?

A: Yes, using pressure data it can estimate altitude with ±1 meter accuracy.
