BMP280 is a high precision, small size, ultra-low power pressure sensor can be used in mobile devices. Its performance, the lowest absolute accuracy up to 0.2Pa, and low power consumption, only 2.7μA. BMP280 uses a powerful 8-pin ceramic leadless chip carrier (LCC) ultra-thin package. This device can be SPI connected and also I2C connected. This does not use a 5V power supply, so you’ll need to run it from the 3.3V pin on your Arduino.
