BME688 v1.0.0

BME688 Arduino Library - Release Notes

Version 1.0.0

Release Date: March 15, 2025
Author: Saurav Sajeev

Overview

This is the initial release of the BME688 Arduino Library, a driver for the Bosch BME688 environmental sensor. The library enables Arduino users to interface with the BME688 to measure temperature, pressure, humidity, and gas resistance. It supports various operating modes, oversampling settings, and gas heater profiles, making it suitable for environmental monitoring and air quality applications.

New Features

• Core Functionality:

  • Read temperature (°C), pressure (Pa), humidity (%), and gas resistance (Ω).
  • Support for Sleep, Forced, and Parallel operation modes (BME_688_SLEEP_MODE, BME_688_FORCED_MODE, BME_688_PARALLEL_MODE).
  • Configurable oversampling settings (1x to 16x) for temperature, pressure, and humidity (BME_688_OSS_1 to BME_688_OSS_16).

• Gas Sensing:

  • Gas resistance measurement with 10 predefined heater profiles (200°C to 380°C) and customizable wait times (60ms to 255ms).
  • Ability to measure gas resistance for a specific target temperature using readGasForTemperature().

• Configuration:

  • Methods to set individual oversampling for temperature, pressure, and humidity (setTemperatureOversampling(), etc.).
  • Debug logging toggle with showLogs().
  • Option to bypass temperature safety limits with ignoreUnsafeTemperatureWarnings() (default limit: 425°C, max: 600°C).

• Safety and Diagnostics:

  • Connection check with isConnected().
  • Calibration parameter handling for accurate sensor readings.
  • Error codes for troubleshooting (e.g., BME688_E_DEV_NOT_FOUND, BME688_E_COM_FAIL).

• Dependencies:

  • Built with Arduino.h and SensorHub.h for seamless integration into Arduino projects.

Changes

• This is the initial release, so no prior versions exist for comparison.
