Bosch BME280

Bosch Sensortec BME280 is a bare LGA-8 combined digital humidity, barometric pressure, and temperature sensor. Tiny 2.5 x 2.5 x 0.93 mm package with I2C (up to 3.4 MHz) and SPI (3- and 4-wire, up to 10 MHz). Independent VDD (1.71-3.6 V) and VDDIO (1.2-3.6 V) supplies suit battery-powered and ultra-low-power designs at 3.6 uA running and 0.1 uA in sleep.
