  • BME280 is a Temperature, Humidity & Pressure Sensor breakout board.
  • Supply voltage VDD main supply voltage range: 1.71 V to 3.6 V
  • BME280 is a precision sensor, is soldered onto PCB. It uses both I2C and SPI (supports 3-, 4-wire SPI) interface. Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz).
  • Pressure: 300-1100 hPa; Temperature: -40 to +85°C; Humidity: 0-100%.
  • This precision sensor is used for measuring barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy.


Description:

BME280 is a precision sensor, not only the pressure and the temperature, this sensor can measure humidity. 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.

Specifications:

VDD main supply voltage range: 1.71 V to 3.6 V

VDDIO interface voltage range: 1.2 V to 3.6 V

Digital interface: I2C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz)

Current consumption 1.8 uA @ 1 Hz humidity and temperature

2.8 uA @ 1 Hz pressure and temperature

3.6 uA @ 1 Hz humidity, pressure and temperature

0.1 uA in sleep mode

Operating range -40 to 85 C, Humidity: 0-100%, Pressure: 300-1100.

Humidity sensor and pressure sensor can be independently enabled/disabled

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.

Package included:

2* BME280 Atmospheric Pressure Sensor Temperature Humidity Sensor Breakout
