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.

 6  Serial.begin(115200);//Serial port initialization
 7  BMP.Atmospheric_init();
 8}
 9
10void loop() {
11  float Temp = BMP.read("Temp");//Define the variable to read the temperature value
12  float Press = BMP.read("Press");//Define variables to read atmospheric pressure values 
13  float Altitude= BMP.read("Altitude");//Define variables to read altitude values
14  Serial.print("Temperature: "); 
15  Serial.print(Temp);//Print the temperature value
16  Serial.println(" ℃"); 
17  Serial.print("Barometric pressure: "); 
18  Serial.print(Press);//Print the barometric pressure value
19  Serial.println(" hPa");
20  Serial.print("Altitude: "); 
21  Serial.print(Altitude); //Print altitude value 
22  Serial.println(" m"); 
23  Serial.println("-------------------"); 
24  delay(2000); //Refresh every two seconds 
25}
