Air quality mapping

Air quality mapping – Breathe the best air and avoid pollution hotspots!

Air quality mapping is the process of measuring and visualizing the concentration of various pollutants in the air across different locations. This technique helps identify pollution hotspots, track changes in air quality over time, and assess the effectiveness of environmental policies. Our innovative and tiny sensors, BMV080 and BME690, deployed in various locations, can gather detailed information about both particulate matter and gaseous pollutants, enabling accurate air quality mapping. This way you can make informed decisions to improve your health. The collected data can also be used to improve environmental conditions and fostering a healthier environment for communities.

Food freshness

Food Freshness – Ensure Quality and Condition of your Food

Food freshness detection helps you track the quality and condition of your food, ensuring that it stays fresh, nutritious, and safe to eat. With our advanced sensors and technology, you can measure critical factors like temperature, humidity, and gas emissions that influence food quality during storage and transport. Maintaining optimal food freshness is essential for preserving taste, texture, and nutritional value, while also reducing the risk of foodborne illnesses and preventing food wastage though the timely detection of spoilage. By using real-time monitoring, you can ensure that your food stays at the ideal conditions to maximize its freshness and extend its shelf life. Food freshness detection provides actionable insights that help you make informed decisions, prevent spoilage, and reduce waste.

FAQs for the BME690

What applications is the BME690 designed for?

The BME690 is designed for applications such as indoor air-quality monitoring, odor and bad-smell detection, detection of unusual gases, spoiled-food detection, smart-home devices and wildfire detection.

Can the BME690 distinguish between different gases?

The BME690 uses a configurable gas-scanning approach combined with AI-based software to classify different gas compositions. Selectivity is achieved by operating the gas-sensitive layer at different temperatures to create characteristic gas fingerprints.

Can developers train the BME690 for custom gas-detection applications?

Yes. Bosch BME AI-Studio can be used to develop, verify and deploy custom gas classification and regression use cases for the BME690.

Which software is used with the BME690?

The BME690 can be used with the Bosch sensor API for raw sensor access and BSEC for fused outputs, gas classification and environmental processing.

Is the BME690 suitable for battery-powered devices?

Yes. BSEC provides an ultra-low-power mode specifically intended for battery-powered or intermittently operated devices over extended periods.
