Feature(may vary by option.)

●The BME280 is the next-generation of sensors, and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but can use either I2C or SPI.
●Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz)
●Pressure: 300-1100 hPa; Temperature: -40 to +85°C ; Humidity: 0-100%
●Supply voltage VDD main supply voltage range: 1.71 V to 3.6 V
●BME280, the precision sensor from , 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

Description:

  • BME280 is a Temperature, Humidity & Pressure Sensor breakout board.
  • The board has selectable I2C address jumper (solder link GS2), I2C pull-up resistors, 7 pin header 2.54mm, and two mounting holes 3.5mm.
  • Default setting of the board; single power rail Vdd=Vdd_IO (solder link GS1), pull-ups resistors (R2, R3) 10k, protocol selector resistor 0ohm (R1), decoupling capacitors 0.1uF on both power supply pins Vdd & Vdd_IO.
  • If you connect board to both power rails VDD_IO 1.8V and VDD 3.3V be sure to remove the power rail jumper GS1!
