bme680_headerThe BME680 is an integrated environmental sensor developed specifically for mobile applications and wearables, where size and low power consumption are key requirements (source). While not yet available on the market, several BME680 samples have been provided under NDA to assist the development of the uRADMonitor-D project and support the monitor’s air quality assertion. The part of the uRADMonitor-D code handling this new sensor is currently under development , but the first tests have shown promising results:

The gas sensor within the BME680 can detect a broad range of gases to measure indoor air quality for personal well being. Gases that can be detected by the BME680 include: Volatile Organic Compounds (VOC) from paints (such as formaldehyde), lacquers, paint strippers, cleaning supplies, furnishings, office equipment, glues, adhesives and alcohol.
The humidity sensor features a best-in-class response time supporting performance requirements for emerging applications such as context awareness, and high accuracy over a wide temperature range.
The pressure sensor is an absolute barometric pres- sure sensor featuring exceptionally high accuracy and resolution at very low noise.
The integrated temperature sensor has been optimized for very low noise and high resolution. It is primarily used for temperature compensation of the gas, pressure and humidity sensors, and can also be used for estima- ting ambient temperature.

The BME680 comes fully calibrated for all sensor components. Its impressive features make it a great addition to the uRADMonitor-D line of products to improve the performance of the portable environmental monitors even further.
