BME280 Integrated Environmental Unit

Bosch’s BME280 measures barometric pressure, humidity and ambient air temperature

Image of Bosch's BME280 Integrated Environmental UnitBosch's BME280 is an integrated environmental sensor developed specifically for mobile applications, where size and low-power consumption are key design constraints. The unit combines individual high-linearity, high-accuracy sensors for pressure, humidity, and temperature in an 8-pin, metal-lid, 2.5 x 2.5 x 0.93 mm³ LGA package, designed for low current consumption (3.6 µA at 1 Hz), long-term stability, and high EMC robustness.

The humidity sensor features an extremely fast response time which supports performance requirements for emerging applications, such as context awareness, and high accuracy over a wide temperature range. The pressure sensor is an absolute barometric pressure sensor which features 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 pressure and humidity sensors and can also be used for estimating ambient temperature. The BME280 supports a full suite of operating modes which provide the flexibility to optimize the device for power consumption, resolution, and filter performance.

The Bosch Sensortec BME280 shuttle-board is a PCB with a BME280 pressure and humidity sensor mounted on it. It allows easy access to the sensors' pins via a simple socket. As all Bosch Sensortec sensor shuttle boards have an identical footprint, they can be plugged into Bosch Sensortec’s advanced development tools such as the development board. Of course, the BME280 shuttle board can also be used for the customer’s own implementations.
