CES - Las Vegas – Bosch Sensortec has expanded its existing family of environmental sensors with the introduction of the BME680 solution that integrates a gas sensor with “best-in-class” air pressure, humidity and ambient air temperature sensing functions in a 3.0 x 3.0 mm² footprint. The gas sensor can detect a broad range of gases to measure indoor air quality, including volatile organic compounds (VOC) from paints (such as formaldehyde), lacquers, paint strippers, cleaning supplies, furnishings, office equipment, glues, adhesives and alcohol.
The BME680 environmental sensor is said to enable new capabilities for portable and mobile devices such as air quality measurement, personalized weather stations, indoor navigation, fitness monitoring, home automation and other applications for the Internet of Things (IoT).
By combining four sensors in one package, the BME680 provides the accurate, detailed real-world data required for many IoT applications, said the company. The device can be used in smart homes, smart offices and buildings, smart energy, smart transportation, HVAC, elderly care and sport/fitness applications.
The BME680’s pressure accuracy of ±0.12 Pa provides precise altitude information to ±1m, making it suited for applications such as indoor navigation with floor level tracking, while the best-in-class response time for measurement of humidity and ambient temperature allows the device to be used in new applications such as personalized weather information and air quality monitoring.
Other features include an offset temperature coefficient of 1.5 Pa/K that enables altitude stability over temperature of 12.6 cm/K, I2C and SPI communication interfaces, three power modes and oversampling rates for pressure and temperature measurements that can be configured separately, and an integrated IIR filter. Proven settings are available for specific applications such as weather logging or indoor navigation.
Samples will be available to select customers in the first quarter of 2015.
