Arduino与Proteus仿真实例-BMP180环境传感器驱动仿真

BMP180环境传感器驱动仿真

BMP180 是 Bosch Sensortec 的新型数字气压传感器，具有非常高的性能，可在智能手机、平板电脑和运动设备等高级移动设备中应用。BMP180 是 BMP XXX 系列的传感器之一。它们都设计用于测量大气压力或大气压力。 BMP180 是一款专为消费类应用设计的高精度传感器。气压只不过是施加在所有物体上的空气重量。空气有重量，只要有空气，就会感受到它的压力。 BMP180 传感器可感应该压力并以数字输出形式提供该信息。温度也会影响压力，因此我们需要温度补偿压力读数。作为补偿，BM180 还具有良好的温度传感器。

在前面的文章中，对BMP180做了介绍，请参考：

Ardunio开发实例-BMP180气压传感器

1、仿真电路原理图

2、仿真代码实现

本次使用到如下开源库：

Adafruit-BMP085-Library

演示代码如下：

#include <Adafruit\_BMP085.h>

/\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* 
 This is an example for the BMP085 Barometric Pressure & Temp Sensor
 Designed specifically to work with the Adafruit BMP085 Breakout 
 ----> https://www.adafruit.com/products/391
 These pressure and temperature sensors use I2C to communicate, 2 pins
 are required to interface

// Connect VCC of the BMP085 sensor to 3.3V (NOT 5.0V!)
// Connect GND to Ground
// Connect SCL to i2c clock - on '168/'328 Arduino Uno/Duemilanove/etc thats Analog 5
// Connect SDA to i2c data - on '168/'328 Arduino Uno/Duemilanove/etc thats Analog 4
// EOC is not used, it signifies an end of conversion
// XCLR is a reset pin, also not used here

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");
    
    // Calculate altitude assuming 'standard' barometric
    // pressure of 1013.25 millibar = 101325 Pascal
    Serial.print("Altitude = ");
    Serial.print(bmp.readAltitude());
    Serial.println(" meters");

    Serial.print("Pressure at sealevel (calculated) = ");
    Serial.print(bmp.readSealevelPressure());
    Serial.println(" Pa");

  // you can get a more precise measurement of altitude
  // if you know the current sea level pressure which will
  // vary with weather and such. If it is 1015 millibars
  // that is equal to 101500 Pascals.
    Serial.print("Real altitude = ");
    Serial.print(bmp.readAltitude(101500));
    Serial.println(" meters");
    
    Serial.println();
    delay(500);
