Gravity: BME688 AI Environmental Sensor (VOC, Temperature, Humidity, Pressure)

The DFRobot Gravity BME688 Environmental Sensor is a top - notch, compact MEMS sensor. It can accurately measure temperature, humidity, barometric pressure, and volatile organic compounds (VOC). With support for I2C/SPI communication protocols, it easily integrates into various systems. It's also a great data source for AI gas analysis, perfect for applications that need precise environmental monitoring and smart gas detection. Ideal for DIY weather stations, portable environmental monitors, smart home systems, and agricultural monitoring. **AI Gas Analysis**: The BME688's AI - driven gas analysis makes it better than the old BME680. It's very useful for air quality monitoring, environmental research, and industrial safety. Using Bosch BME AI - Studio and BSEC2 - Arduino library, you can do customized AI gas analysis to detect specific gas profiles. **Highly Accurate Sensing**: It improves temperature measurement accuracy to ±0.5°C. This makes it a great choice for applications needing highly accurate environmental data, like scientific experiments, climate research, and industrial environmental monitoring. **Advanced Air Quality Monitoring**: It's excellent at indoor air quality monitoring. It can detect harmful VOCs and give real - time data for smart homes. Its built - in heating layer reduces ambient interference for stable and accurate measurements. **Applications**: DIY weather stations, portable environmental monitoring devices, smart home systems, agricultural monitoring. **Specification**: - **Power Requirements**: Operating Voltage: 3.3 to 5V DC; Operating Current: 5mA (25mA with VOC Measurement Enabled). - **Output Signal**: Interface Options: I2C/SPI. - **Temperature Sensor**: Measurement Range: - 40 to +85°C; Accuracy: ±0.5°C (0 to 65°C). - **Humidity Sensor**: Measurement Range: 0 to 100% Relative Humidity (R.H.); Accuracy: ±3% R.H. (20 to 80% R.H. at 25°C). - **Barometric Pressure Sensor**: Measurement Range: 300 to 1100 hPa; Accuracy: ±0.6 hPa (300 to 1100 hPa at 0 to 65°C). - **Physical Dimensions**: Module Size: 30 mm x 22 mm / 1.18 inches x 0.87 inches. **Documents**: Product wiki, Pinout, Tutorial, Arduino library API list, Compatible test, Schematic, PCB layout, BME688 datasheet.

Using the Gravity BME688 Environmental Sensor is quite easy. First, connect it to your system using either the I2C or SPI communication protocol as per your needs. Make sure to provide the correct power supply within the range of 3.3 to 5V DC. The sensor will start collecting data on temperature, humidity, barometric pressure, and VOCs right away. When using it for AI gas analysis, you can use the Bosch BME AI - Studio and BSEC2 - Arduino library to customize the analysis according to the specific gas profiles you want to detect. For maintenance, keep the sensor clean and avoid exposing it to extreme conditions. The built - in heating layer helps reduce interference, but still, try to place it in a stable environment. Also, be aware of the power consumption. When VOC measurement is enabled, the current goes up to 25mA, so plan your power supply accordingly.
