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

The DFRobot Gravity BME688 Environmental Sensor is an advanced, compact MEMS sensor that provides accurate measurements of temperature, humidity, barometric pressure, and volatile organic compounds (VOC). It supports I2C/SPIcommunication protocols, which facilitate integration with various systems. It also serves as a data source for AI gas analysis, making it an ideal choice for applications requiring precise environmental monitoring and intelligent gas detection. This sensor is well-suited for DIY weather stations, portable environmental monitoring devices, smart home systems, and agricultural monitoring.

AI Gas Analysis

The BME688’s AI-driven gas analysis capability sets it apart from the previous BME680 model. It is particularly valuable for air quality monitoring systems, environmental research, and industrial safety. Using the Bosch BME AI-Studio and BSEC2-Arduinolibrary, customized AI gas analysis can be implemented to detect and analyze specific gas profiles.

Highly Accurate Environmental Sensing

The BME688 sensor enhances the precision of temperature measurements, boasting an accuracy of ±0.5°C. These improvements render the sensor ideal for applications requiring highly accurate environmental data, including scientific experiments, climate research, and industrial environmental monitoring.

Advanced Air Quality Monitoring

The Gravity BME688 excels in indoor air quality monitoring, detecting harmful VOCs and providing real-time data for smart homes. Its built-in heating layer ensures stable, accurate measurements by minimizing ambient interference.
