Arduino Home Weather Station with BME280 using I2C

by

Materials

  • Arduino Uno
  • BME280 Sensor
  • Breadboard and Jumper Wires

Instructions

  1. Connect the BME280 sensor to the Arduino using I2C.
  2. Upload the following code to your Arduino:
Copy Code 


#include <"Wire.h">

#include <"Adafruit_Sensor.h">

#include <"Adafruit_BME280.h">

Adafruit_BME280 bme;

void setup() {

    Serial.begin(9600);

    if (!bme.begin()) {

        Serial.println(“Could not find a valid BME280 sensor, check wiring!”);

        while (1);

    }

}

void loop() {

    float temperature = bme.readTemperature();

    float humidity = bme.readHumidity();

    float pressure = bme.readPressure() / 100.0F;

    Serial.print(“Temperature: “);

    Serial.print(temperature);

    Serial.print(” C, “);

    Serial.print(“Humidity: “);

    Serial.print(humidity);

    Serial.print(” %, “);

    Serial.print(“Pressure: “);

    Serial.print(pressure);

    Serial.println(” hPa”);

    delay(2000);

}

Explanation

This code reads temperature, humidity, and pressure from the BME280 sensor and prints the data to the serial monitor. It’s useful for building a weather monitoring station.

Conclusion

This home weather station project offers insights into environmental monitoring and data collection, providing valuable information for various applications.
