Components: Using BMP 180 Sensor

In here, you'll learn hw to use a BMP180 sensor to outlay accurate altitude, pressure and temperature data.

You will need:

• Arduino Uno or Arduino Nano
• Small Breadboard
• Jumper wires
• BMP 180 sensor module

You will need:

• a computer running Mac OS or Windows 10 or higher.
• Arduino IDE software

Firstly, wire the circuit in correlation to the circuit diagram above.

Make sure:

• VCC - 5V
• GND - GND (any of the ground connections)
• SCL - A4
• SDA - A5

You will need to upload a code file to IDE via an Arduino cable.

In order for the code to work you will need to download a library.

you need the Adafruit BMP085 unified by Adafruit.

The code is below:

#include <Wire.h>

#include <Adafruit_BMP085.h>

#define seaLevelPressure_hPa 1013.25

Adafruit_BMP085 bmp;

void setup() {

Serial.begin(9600);

if (!bmp.begin()) {

Serial.println("Could not find a valid BMP085 sensor, check wiring!");

while (1) {}

}

}

void loop() {

Serial.print("Temperature = ");

Serial.print(bmp.readTemperature());

Serial.println(" *C");

Serial.print("Pressure = ");

Serial.print(bmp.readPressure());

Serial.println(" Pa");

Serial.print("Altitude = ");

Serial.print(bmp.readAltitude());

Serial.println(" meters");

Serial.print("Pressure at sealevel (calculated) = ");

Serial.print(bmp.readSealevelPressure());

Serial.println(" Pa");

Serial.print("Real altitude = ");

Serial.print(bmp.readAltitude(seaLevelPressure_hPa * 100));

Serial.println(" meters");

Serial.println();

delay(500);

}

or you can open the Arduino file below.
