QB103 Barometric Pressure Sensor

1.Product Introduction

The Barometric Pressure Sensor adopts BMP280 chip and integrates two main functions of temperature detection and atmospheric pressure detection. It can measure atmospheric pressure to provide information on current altitude or air pressure, and can also be able to measure ambient temperature and provide accurate temperature data for temperature compensation or other environmental monitoring applications. In navigation applications, the barometer can also enhance the GPS positioning effect, or combine with IMU sensors to achieve three-dimensional indoor navigation.

Application reference: weather station, indoor navigation, pneumatic altimeter, UAV, etc.

4.Sample Code

#include <ACB_Atmospheric.h>

ACB_Atmospheric BMP;

void setup() {
  Serial.begin(115200);//Serial port initialization
  BMP.Atmospheric_init();
}

void loop() {
  float Temp = BMP.read("Temp");//Define the variable to read the temperature value
  float Press = BMP.read("Press");//Define variables to read atmospheric pressure values 
  float Altitude= BMP.read("Altitude");//Define variables to read altitude values
  Serial.print("Temperature: "); 
  Serial.print(Temp);//Print the temperature value
  Serial.println(" ℃"); 
  Serial.print("Barometric pressure: "); 
  Serial.print(Press);//Print the barometric pressure value
  Serial.println(" hPa");
  Serial.print("Altitude: "); 
  Serial.print(Altitude); //Print altitude value 
  Serial.println(" m"); 
  Serial.println("-------------------"); 
  delay(2000); //Refresh every two seconds 
}

5.Test Result

When you successfully connect the wiring according to the wiring diagram and successfully upload the correct program, the serial port monitor will print the current atmospheric temperature, atmospheric pressure intensity and altitude data of the atmospheric pressure sensor.
