Overview

Barometric sensor is ideal for measuring various weather conditions.

This sensor has high accuracy and low cost making it an ideal solution for precision pressure measurements of up to ± 1 hPa and a temperature of up to ± 1.0oC. Because the pressure changes with altitude and pressure measurements are very accurate, you can use this sensor and the altimeter ± 1 meter accuracy.


Specifications

  • Power supply: 3 V to 5V
  • Communication: I2C or SPI
  • Pressure accuracy: ± 1 hPa
  • Temperature Accuracy: ± 1.0oC
  • Dimensions: 19.2mm x 17.9mm x 2.9mm / 0.8 "x 0.7" x 0.1 "
  • Weight: 1.3 g

Pin supply:

  • Vin- supply pin. Since the image using 3V DC, the board has a built-in voltage regulator that receives 3-5V DC and converts them to 3V. To use the module to be powered from the same voltage as the Arduino board.
  • 3Vo - this is the output from 3.3V regulator. It can provide up to 100mA
  • GND - Point Table

SPI pins:

All pins have level shift circuit to bring to a logical level 3 V to 5 V. Use any logical level is Vin pin.

  • SCK - SPI Clock pin, entry
  • SDO - Serial Data Out / Master In Slave Out pin, for sending data from the processor BMP183
  • SDI - Serial Data In / Master Out Slave In pin, for sending data from the processor to BMP183
  • CS - Chip Select pin, entry form, must be connected to "low" to start transmission SPI

To connect more BME280 the same microprocessor must use the same pin SDI, SDO and SCK.

I2C pin:

  • SCK - is also the I2C clock pin, pin connects to the microprocessor clock.
  • SDI - is also pin I2C time data terminal connects to the microprocessor

For more details check the attached datasheet.

Schimbati adresa I2C in libraria Adafruit

Foarte bun senzorul. Merge cu lbraria de la Adafruit, dar doar dupa ce schimbati adresa I2C din librarie. Urmati instructiunile de aici http://davidstein.cz/2017/09/30/arduino-bme280-could-not-find-a-valid-bme280-sensor-solved/

Raspberry Pi 3B - Python 3

Senzorul functioneaza pe RPI 3b cu libraria BME280 de la Adafruit cu precizarea ca trebuia facuta modificarea spusa de George M si anume in fisierul "Adafruit_BME280.py" inlocuiti BME280_I2CADDR = 0x77 cu BME280_I2CADDR = 0x76.

Adafruit

Merge si cu libraria Adafruit dar cu ceva modificari. Le-am gasit aici: http://davidstein.cz/2017/09/30/arduino-bme280-could-not-find-a-valid-bme280-sensor-solved/

ATENȚIE! Placa nu are convertor de tensiune incorporat, așa cum este scris în specificațiile de pe site. Se alimentează la maxim 3,6 V și pentru a comunica pe I2C are nevoie de convertor de semnal de la 3.3 la 5 VCC.

Produs foarte bun.

Senzorul BMP280 GY este un senzor foarte bun dar si foarte usor de folosit.

Sparkfun,confirm si SPI

functioneaza ok si pe interfata SPI cu libraria sparkfun. Varianta asta BMP280 nu citeste si umiditatea, doar presiunea si temperatura. Pentru functii complete umi-termo-presiune alegeti BME280.Librariile sparkfun merg si pentru ea numai ca apelarea functiilor legate de umiditate intoarce un zero....

Sparkfun (nu Adafruit)

Nu pare sa functioneze cu libraria de la Adafruit, dar la mine a mers cu cea de la Sparkfun, I2C addr=76:
