How to Use the BME280 with Arduino Nano Every

In this tutorial, we'll explore how to connect the BME280 sensor to the Arduino Nano Every. By combining these two powerful components, you can unlock a wealth of environmental data for your projects. Whether you're a beginner or an experienced Arduino enthusiast, this guide will walk you through the simple steps required to establish the connection and start collecting valuable data. Let's dive in and unleash the potential of the BME280 and Arduino Nano Every!

Step 1-) Make a Connection as Follows

Step 2-) Code

In the Arduino IDE make sure you are connected to your board.

Go to Library Manager and download the Adafruit BME package

Once the package is downloaded you can open the example code they have in

File > Examples > Adafruit BME280 Library > bme280test

I modified the code slightly shown here

/***************************************************************************
  This is a library for the BME280 humidity, temperature & pressure sensor

  Designed specifically to work with the Adafruit BME280 Breakout
  ----> http://www.adafruit.com/products/2650

  These sensors use I2C or SPI to communicate, 2 or 4 pins are required
  to interface. The device's I2C address is either 0x76 or 0x77.

    Serial.begin(9600);
    while(!Serial);    // time to get serial running
    Serial.println(F("BME280 test"));

    if (!status) {
        Serial.println("Could not find a valid BME280 sensor, check wiring, address, sensor ID!");
        Serial.print("SensorID was: 0x"); Serial.println(bme.sensorID(),16);
        Serial.print("        ID of 0xFF probably means a bad address, a BMP 180 or BMP 085\n");
        Serial.print("   ID of 0x56-0x58 represents a BMP 280,\n");
        Serial.print("        ID of 0x60 represents a BME 280.\n");
        Serial.print("        ID of 0x61 represents a BME 680.\n");
        while (1) delay(10);
    }
    
    Serial.println("-- Default Test --");
    delayTime = 1000;

    Serial.println();
}


void loop() { 
    printValues();
    delay(delayTime);
}


void printValues() {
    Serial.print("Temperature = ");
    Serial.print(bme.readTemperature());
    Serial.println(" °C");

    Serial.print("Pressure = ");

    Serial.print(bme.readPressure() / 100.0F);
    Serial.println(" hPa");

    Serial.print("Approx. Altitude = ");
    Serial.print(bme.readAltitude(SEALEVELPRESSURE_HPA));
    Serial.println(" m");

    Serial.print("Humidity = ");
    Serial.print(bme.readHumidity());
    Serial.println(" %");

    Serial.println();
}

I simply added status = bme.begin(0x76);

This allows us to use the bme280 sensor I have in the description. If this does not work for your BME280 try using 77 instead of 76 and that should work.

Another thing we have to adjust is the SEALEVELPRESSURE_HPA. You can get this value by googling your city; it may not be available in your area but this is what the algorithm needs to determine your altitude more accurately.

Once you have this setup you should be able to upload it to the Arduino to start getting values.

Conclusion:

Let me know if you have any issues with altitude or any other questions/comments. Hope you enjoyed the tutorial do not forget to subscribe to my channel for more simple sensor tutorials to help you in your sensor journeys.
