Senzor temperatura/umiditate/presiune

BME280 Atmospheric Pressure Sensor Temperature Humidity Sensor Breakout for Arduino  BMP280 sensor Replace BMP180

Description:

BME280, the precision sensor from Bosch, is soldered onto PCB. Not only the pressure and the temperature, this sensor can measure humidity.

It uses both I2C and SPI (supports 3-, 4-wire SPI) interface

Make sure to put SDO to high to get address 0x77. This will work with Adafruit BME280 library perfectly.
