Boardoza BME688 Environmental Sensor Breakout Board
The Boardoza BME688 Breakout Board is a compact environmental sensing solution built around the Bosch Sensortec BME688 4-in-1 sensor. It combines gas, barometric pressure, temperature, and relative humidity sensing in a single device while delivering high accuracy, fast response times, and low power consumption. When used with Bosch’s AI software ecosystem, the integrated gas sensor can detect a wide range of volatile organic compounds (VOCs) and volatile sulfur compounds (VSCs). Designed for both hobbyists and professional developers, the board supports I²C communication by default as well as SPI, making it compatible with a wide range of microcontrollers and embedded systems. It is ideal for air quality monitoring, smart home automation, HVAC (heating, ventilation, and air conditioning) systems, weather stations, indoor environmental monitoring, industrial sensing, food freshness detection, and AI-powered gas classification applications using Bosch BME AI-Studio.
Key Features
- 4-in-1 Environmental Sensing: Measures gas, barometric pressure, relative humidity, and temperature using the Bosch Sensortec BME688 sensor.
- AI-Powered Gas Classification: Compatible with Bosch BME AI-Studio for training custom gas detection and classification algorithms.
- VOC and VSC Detection: Detects Volatile Organic Compounds (VOCs), Volatile Sulfur Compounds (VSCs), smells, and various gas mixtures.
- Dual Communication Interface: Supports I²C communication by default and selectable SPI communication.
- 3.3V and 5V System Compatibility: Designed for easy integration with commonly used microcontrollers and development boards.
- Low-Power Operation: Suitable for battery-powered and continuously operating environmental monitoring systems.
- Wide Application Range: Suitable for indoor air-quality monitoring, HVAC systems, weather stations, smart-home applications, odor detection, and food-freshness analysis.
