Datasheet

An integrated environmental sensor specifically developed for wearables and mobile applications with its space-saving design and low power consumption is now available from Rutronik. With the BME680, Bosch Sensortec is expanding its product portfolio to include the first integrated MEMS sensor measuring individually, highly linear, and precise, gas, air pressure, humidity, and temperature.

The BME680’s gas sensor detects a number of different gases, including volatile organic compounds in paints containing formaldehyde, varnishes, paint strippers, cleaning agents, furniture, office equipment, adhesives, and alcohol. With accuracy of ±0.12hPa and a TCO of 1.5Pa/K, the sensor features a precise barometer.

High-resolution and low-noise sensors for measuring humidity and temperature complete the package, making it suitable for new application areas such as home automation, indoor navigation, personalised weather stations, or sport and fitness tools.

The BME680 supports the I²C and SPI buses (three- or four-wire), is compatible with a wide range of VDD and VDDIO supply voltages, and can work in standard, forced, and sleep mode. It comes fully calibrated; an air pressure calculation can also be carried out at a later stage using the ACP 2.0 software from Bosch Sensortec.

The sensor is housed in LGA package measuring 3.0x3.0x0.95mm³. The design supports electromagnetic compatibility (EMC), longevity, and optimal power consumption in various operating modes.

To make the set-up process as simple as possible, standard settings for common applications such as weather monitoring, staircase/elevator detection, indoor navigation, and drop detection are already available, but the data rate, noise, response time, and power consumption can also be individually adjusted.
