SparkFun Environmental Sensor Breakout – BME680 (Qwiic)

The SparkFun BME680 Environmental Sensor is a breakout that combines a gas sensor with temperature, humidity and barometric pressure sensing for a complete environmental sensor in a single package. The gas sensor on the BME680 can detect a wide variety of volatile organic compounds (or VOC for short) to monitor indoor air quality. Combine that with precise temperature, humidity, and barometric pressure and the BME680 can work as a completely standalone environmental sensor all in a 1in. x 1in. breakout! The sensor communicates via either I2C or SPI. We’ve broken out the I2C pins to our Qwiic system so no soldering is required to connect it to the rest of your system but if you would prefer, both the I2C and SPI pins are also broken out to standard 0.1in.-spaced pins. Uses I2C interface (Qwiic-enabled) I2C Addresses: 0x77 (Default) or 0x76 2x Qwiic Connectors Operating voltage range 1.71V – 3.6V Typically 3.3V if using the Qwiic cable Relative humidity Operating range: 0% to 100% Absolute Accuracy: ±3%RH Resolution: ±0.008%RH Temperature Operating range: -40°C to +85 °C Absolute Accuracy: ±0.5°C to ±1.0°C Resolution: 0.01°C Pressure Operating range: 300hPa – 1100hPa Relative accuracy: ±12Pa (25°C to 40°C @ constant RH) Absolute accuracy: ±60Pa (0°C to 65°C) Resolution: 0.18PA, highest oversampling Gas Resolution of gas sensor resistance: 0.05% to 0.11% Typical current consumption (varies based on mode and active sensor) 2.1µA to 18mA 0.15 µA (sleep mode)
