BMP280 Digital Pressure Sensor Breakout Board is based on Bosch’s proven Piezo-resistive pressure sensor technology featuring high EMC robustness, high accuracy and linearity and long-term stability.
The chip can be programmed as a 3 or 4-wire SPI interface, or even as 2 wire I2C bus. With a power supply and logic level voltage of 1.8-3.6V and current consumption of just about 0.003mA, it is perfectly suitable for battery-operated microcontroller applications like a mobile data logger.

The size of the PCB is just 15 x 12 x 2.5mm, and the weight is only 0.55g (without header pins). A pin header is included in the shipment, but not already assembled.

A broad range of drivers (libraries) and example code (sketches) is available for example for Arduino.

The BMP280 is an absolute barometric pressure sensor specially designed for mobile applications. The sensor module is housed in an extremely compact 8-pin metal-lid LGA package with a footprint of only 2.0 2.5 mm2 and 0.95 mm package height. Its small dimensions and its low power consumption of 2.7µA @1Hz allow the implementation in battery-driven devices such as mobile phones, GPS modules or watches.

As the successor to the widely adopted BMP180, the BMP280 delivers high performance in all applications that require precise pressure measurement. The BMP280 operates at lower noise, and supports new filter modes and an SPI interface within a footprint 63% smaller than the BMP180. The emerging applications of indoor navigation, health care or GPS refinement require high relative accuracy and a low TCO at the same time. BMP180 and BMP280 are perfectly suitable for applications like floor detection since both sensors feature excellent relative accuracy is 0.12 hPa, which is equivalent to a 1 m difference in altitude.
