BMP280 Based Weather Station using Arduino and OLED Display

The weather station is an interesting project for beginners and very useful for specialist manufacturers. It is simple to build and in general provides sufficiently accurate and useful weather data. For today’s tutorial, we will build another BMP280 Based Weather Station using Arduino and OLED Display. Using the BMP280 sensor we will be able to monitor the temperature, atmospheric pressure, and altitude.

Table Of Contents

The Arduino reads the temperature, pressure, and altitude values from the BMP280 sensor and prints them on a 0.96″ (SSD1306) OLED display (128×64 pixel).

BMP280 Based Weather Station using Arduino and OLED Display

The BMP280 is Bosch’s next-generation sensor and is an upgrade of their previous sensors, including the BMP085, BMP180, and BMP183. The BMP280 is excellent for weather sensing with low noise of 0.25 meters. The conversion rate is as fast as the previous sensors. Additionally, the BMP280 can be used in both I2C and SPI modes. It also has an onboard voltage regulator and a level shifter, which means it can be used with either a 3volt or 5volt supply.

Along with the BMP280, we will use the I2C-based, 0.96″ (128×62 Pixel) OLED Display to show the values obtained from the BMP280 sensor.

At the end of this tutorial, you will also learn how to interface BMP280 or any other I2C device with Arduino and display data in the OLED display.

BMP280 Sensor Measures

As I already mentioned above, The BMP280 is a Barometric pressure and digital Temperature sensor that can measures:

  • Temperature
  • Barometric pressure
  • Altitude

Interface BMP280 Sensor & OLED Display with Arduino

Now, Let’s wire the BMP280 sensor and 0.96″ OLED Display with the Arduino. The Connections are fairly simple because the OLED and the BMP280 both communicate with the Arduino via I2C mode. This means we can connect both modules to the same (I2C) pins on the Arduino. Connect the components as shown in the schematics below.

Programming Arduino for BMP280 based Weather Station

To write the program code for this weather station project, we will use four key libraries; the Adafruit BMP280 library, the Adafruit Unified Sensor Library, the Adafruit SSD1306 library, and U8Glib library. These four libraries can be downloaded from the Arduino Library Manager or via the download link attached below.

The Adafruit BMP280 contains functions that make it easy to write the code. It will obtain the parameters from the sensor while the U8Glib and SSD1306 libraries are used to easily display texts and graphics on the OLED display.

 #include <Wire.h>
 #include <SPI.h>
 #include <Adafruit_BMP280.h>
 #include <Adafruit_Sensor.h>

 #define BMP_SCK 13

Creating Splash Screen for BMP280 based Weather Station on OLED display using Arduino

BMP280 Based Weather Station using Arduino and OLED Display

It reads the current pressure from BMP280 sensor and display it on the OLED Display.

void draw_4(void){
 pressure=bmp.readPressure()/100;
 delay(1);
 u8g.setPrintPos(32,10);
 u8g.print("Pressure");
 u8g.setPrintPos(65,45);

 u8g.setPrintPos(70,60);
 u8g.print("hPa");
 u8g.drawBitmapP( 0, 15, 6, 48,presure);
 }

This code display the current temperature on display by grabbing them from BMP280 module.

void draw_2(void){
 u8g.setFont(u8g_font_8x13);
 u8g.setPrintPos(0,10);
 u8g.print(" Temperature");
 u8g.setPrintPos(55,40);
 u8g.print(temp);
 u8g.setPrintPos(97,40);
 u8g.print("C");
 u8g.drawBitmapP( 0, 17, 6,48,temperature);
 }

Displays the weather forecast using barometric pressure value.

void draw3(void){
 u8g.setPrintPos(3,10);
 u8g.print("Weather Forecast");
 if ((pressure<=1000.59)&&(pressure>998.5)){
 u8g.drawBitmapP( 10, 15, 6, 48,cloudy);
 u8g.setPrintPos(60,45);
 u8g.print("Cloudy");
 }
 else if((pressure<998.5)&&(pressure>996.5))
 {
 u8g.drawBitmapP( 10, 15, 6, 48,rain);
 u8g.setPrintPos(66,38);
 u8g.print("Rain");}
 else if((pressure>1000.6)&&(pressure<1050)) { u8g.drawBitmapP( 5, 15, 6, 48,sunny); u8g.setPrintPos(50,45); u8g.print("Clear Sky");} else if((pressure>990)&&(pressure<=996.4))
 {
 u8g.drawBitmapP( 5, 15, 6, 48,storm);
 u8g.setPrintPos(60,45);
 u8g.print("Storm");}
 else{
 u8g.setPrintPos(40,40);
 u8g.print("Error!");
 }
 }

In the setup part, we have started a serial monitor for debugging errors. then, we test the BMP280 sensor working or not. Finally, display all the weather station data by auto changing screen with sliding animation every 2 seconds.

void setup() {
 Serial.begin(9600);
 Serial.println(F("BMP280 test"));
 if (!bmp.begin()) {
 Serial.println(F("Could not find a valid BMP280 sensor, check wiring!"));
 while (1);
 }
 u8g.firstPage(); // first page
 do {
 draw();
 }
 while( u8g.nextPage() );
 delay(2000);
 }
 void loop() {
 temp=bmp.readTemperature();
 u8g.firstPage(); // Next page
 do {
 draw_2();
 }
 while( u8g.nextPage() );
 delay(2000);
 u8g.firstPage(); // Next page
 do {
 draw_4();
 }
 while( u8g.nextPage() );
 delay(2000);
 u8g.firstPage(); // Next page
 do {
 draw3();
 }
 while( u8g.nextPage() );
 delay(2000);
 }

After successful upload of the program code, open the serial monitor. You can see the BMP280 Sensor test is running. If you see the error message like: “Could not find a valid BMP280 sensor, check wiring” then you need to change your BMP280 default I2C address in the Adafruit_BMP280.h file.

Edit BMP280 I2C address

The Adafruit_BMP280.h file located at: Documents\Arduino\libraries\Adafruit_BMP280_Library. For reference, check the image below.

Now, re-upload the code and check your Serial Monitor. Finally, you got the temperature, barometric pressure data, and weather forecasting data on OLED Display.

Demonstration: BME280 based Weather Station

Now, if you have followed all the mentioned steps and connected everything accordingly, then you should see the weather station data on your OLED display without any errors.
