Reading BME280 - Arduino

Reading BME280 - Arduino:
Hardware required:
- BME280 Sensor board
- Arduino UNO

Wiring:

Install BME280 Libraries:
Github Page: BME280
To install the library, from Arduino IDE (2.3.x),  Click on Libraries icon on the left pane.
Search for BME280 and install Bme280 by Eduard Malokhvii.

From File -> Examples -> BME280 ->  Click on “TwoWire” example.
 

TwoWire.ino Script:

#include <Arduino.h>
#include <Bme280.h>

Bme280TwoWire sensor;


void setup() {
  Serial.begin(9600);
  //Wire.begin (D1, D2); //Comment this line
  Wire.begin();          //Add this line

  Serial.println();

  sensor.begin(Bme280TwoWireAddress::Primary);
  sensor.setSettings(Bme280Settings::indoor());
}

void loop() {
  auto temperature = String(sensor.getTemperature()) + " °C";
  auto pressure = String(sensor.getPressure() / 100.0) + " hPa";
  auto humidity = String(sensor.getHumidity()) + " %";

  String measurements = temperature + ", " + pressure + ", " + humidity;
  Serial.println(measurements);

  delay(1000);
}

Note:
Change Wire.begin(D2, D1); to Wire.begin(); in the script.

Select the board (UNO) and your com-port , Compile and upload.
Open COM port Monitor and see the logging:

Note: hPa - hectoPascals
Atmo Pressure is measured in hectoPascals (hPa), also called millibars.
Standard pressure at sea level is defined as 1013hPa.

one hPa = one millibar = one thousandth of a “bar” (1/1000)
1hPa = 1 Milli Bar (mb).
