This library adds support for both the BMP280 and BME280 sesnors from Bosch. The BME is virtually identical to the BMP280 aside from some slight register changes and adding support for a humidity sensor. The BMP280 is an absolute barometric pressure sensor especially 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 2.7 μA @1Hz allow the implementation in battery driven devices such as mobile phones, GPS modules or watches. 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 These drivers support both I2C and SPI operation. When using SPI on an Edison with the arduino breakout board, you must specify a CS of -1 to the constructor, and connect the chip's CS pin to arduino pin 10.
