+% brand new and high quality
+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
+Specifications:
+Supply Voltage: 1.8 - 5V DC
+Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz)
+Operational Range:
+Temperature: -40 to +85°C
+Humidity: 0-100%
+Pressure: 300-1100 hPa
+Resolution:
+Temperature: 0.01°C
+Humidity: 0.008%
+Pressure: 0.18Pa
+Accuracy:
+Temperature: +-1°C
+Humidity: +-3%
+Pressure: +-1Pa
+I2C address
+SDO LOW ： 0x76
+SDO HIGH：　0x77
