GY-BME280-5V BME280 Digital Sensor Temperature Humidity Barometric Pressure Sensor

description

ME-BME280 is a breakout board with Bosch Sensortec ME280 temperature, humidity and pressure sensors.

This evaluation board has optional I2C address jumper (soldering link GS2), I2C pull-up resistor, 7-pin header connector 2.54mm and two 3.5mm mounting holes.

Board default settings; single power rail Vdd = Vdd_IO (welding link GS1), pull-up resistors (R2, R3) 10k, protocol selector resistor 0ohm (R1), two power pins Vdd and Vdd_IO Coupling capacitor 0.1uF.

If you connect the board to both power rails VDD_IO 1.8V and VDD 3.3V, make sure to remove the power rail jumper GS1!

 

BME280 function

-Packing 2.5mm x 2.5mm x 0.93mm metal cover LGA

-Digital interface I2C (up to 3.4 MHz) and SPI (3 and 4 lines, up to 10 MHz)

-Supply voltage VDD main supply voltage range: 1.71 V to 3.6 V

VDDIO interface voltage range: 1.2 V to 3.6 V

-1.8 uA current consumption at 1 Hz humidity and temperature

2.8 uA @ 1 Hz pressure and temperature

3.6 uA at 1 Hz humidity, pressure and temperature

0.1 uA in sleep mode

-Working range -40 ... + 85 C, 0 ... 100% rel. Humidity 300… 1100 hPa- Humidity and pressure sensors can be independently enabled / disabled

BMP280 sensor, which is an environmental sensor with temperature and air pressure, is the next generation of BMP085 / BMP180 / BMP183 upgrade products, which can further enhance competitiveness. The sensor is perfect for a variety of weather sensing and can even be used in I2C and SPI!

 

This high-precision sensor is the best low-cost, high-precision sensing solution for measuring atmospheric pressure (absolute accuracy ± 1 hPa) and temperature (accuracy ± 1.0 ° C). Since pressure varies with altitude and the pressure measurement is very good, you can also use it as an altimeter with an accuracy of ± 1 meter

 

The BME280 sensor is an upgraded version of the BMP085 / BMP180 / BMP183-with low altitude noise of 0.25m and the same fast transition time. It has the same specifications, but can use I2C or SPI. For easy wiring, use I2C. If you want to connect a bunch of sensors without having to worry about I2C address conflicts, use SPI.
