The BME680 is an integrated environmental sensor developed specifically for mobile applications and wearables, where size and low power consumption are key requirements (source). Thanks to Bosch Sensortec, several BME680 samples have been provided to assist further 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:
This tiny sensor is 4 in 1, and track the following parameters:
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. This is a Metal Oxide MEMS sensor, and you can read more on this technology here.
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 estimating 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.
