BME280 Environmental sensor


The BME280 is as combined digital humidity, pressure and temperature sensor based on proven sensing principles. The sensor module is housed in an extremely compact metal-lid LGA package with a footprint of only 2.5 × 2.5 mm² with a height of 0.93 mm. Its small dimensions and its low power consumption allow the implementation in battery driven devices such as handsets, GPS modules or watches. The BME280 is register and performance compatible to the Bosch Sensortec BMP280 digital pressure sensor (see chapter 5.2 for details).

The BME280 achieves high performance in all applications requiring humidity and pressure measurement. These emerging applications of home automation control, in-door navigation, health care as well as GPS refinement require a high accuracy and a low TCO at the same time.


BME280 pinout


1. Digital interface I²C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz)
2. Humidity sensor and pressure sensor can be independently enabled / disabled
3. Register and performance compatible to Bosch Sensortec BMP280 digital pressure sensor
4. RoHS compliant, halogen-free, MSL1

Typical applications

1. Context awareness, e.g. skin detection, room change detection
2. Health monitoring / well-being
3. GPS enhancement (e.g. time-to-first-fix improvement, dead reckoning, slope detection)
4. Indoor navigation (change of floor detection, elevator detection)
5. Outdoor navigation, leisure and sports applications
6. Weather forecast
7. Vertical velocity indication (rise/sink speed)
