## Description

The Gravity BME688 is an advanced MEMS environmental sensor from Bosch that measures temperature, humidity, barometric pressure, and volatile organic compounds (VOC) in a single compact module. It supports both I²C and SPI interfaces via a Gravity connector, making integration with Arduino and other microcontrollers straightforward. What sets the BME688 apart from the earlier BME680 is its AI-driven gas analysis capability. Using the Bosch BME AI-Studio and BSEC2 Arduino Library, you can train custom gas profiles to detect and classify specific VOCs — ideal for air quality monitoring, environmental research, and industrial safety applications. Key Features 4-in-1 Environmental Sensing – Temperature, humidity, barometric pressure, and VOC AI Gas Analysis – Train custom gas detection profiles via Bosch BME AI-Studio High Accuracy – ±0.5 °C temperature, ±3% RH humidity, ±0.6 hPa pressure I²C/SPI Interface – Gravity connector for plug-and-play wiring Wide Voltage Support – 3.3–5 V DC Built-In Heater – Minimises ambient interference for stable VOC readings Specifications Sensor IC – Bosch BME688 Operating Voltage – 3.3–5 V DC Operating Current – 5 mA (25 mA with VOC measurement enabled) Interface – I²C / SPI (Gravity connector) Temperature Range – −40 to +85 °C (±0.5 °C accuracy, 0–65 °C) Humidity Range – 0–100% RH (±3% RH accuracy, 20–80% RH at 25 °C) Pressure Range – 300–1100 hPa (±0.6 hPa accuracy, 0–65 °C) Module Dimensions – 30 × 22 mm Ideal For DIY weather stations Indoor air quality monitoring and smart home systems Portable environmental monitoring devices Agricultural climate sensing Scientific experiments and climate research Resources Product Wiki (includes pinout, tutorial, and API reference) BME688 Datasheet (PDF) Schematic (PDF) PCB Layout (PDF) BSEC2 Arduino Library (GitHub) Bosch BME AI-Studio Package Contents 1× Gravity BME688 Environmental Sensor Module
