This sensor measures air pressure and temperature and is based on the Bosch BMP280 sensor.

Technical Information

• Operating pressure 300 to 1100 hPa
• Relative precision ±0.12 hPa
• Absolute precision ±1 hPa
• Operating supply current 2.7μA at 1 Hz sampling frequency
• Dimensions: 25mm x 25mm x 9mm
• Weight: 2.4 g

Programming (Arduino)

#include "SenseBoxMCU.h"
#include <SPI.h>

BMP280 bmp_sensor;

void setup() {
  Serial.begin(9600);
  bmp_sensor.begin();
}

void loop() {
    Serial.print("Pressure: ");
    Serial.println(bmp_sensor.getPressure());
    Serial.print("Temperature: ");
    Serial.println(bmp_sensor.getTemperature());
    Serial.print("Altitude: ");
    Serial.println(bmp_sensor.getAltitude(1000));
}

Programming (Blockly)

In Blockly the sensor can be read out via the following block:

In the block you can choose between the different parameters of the air pressure/temperature sensor:

• Air pressure in Pascal (Pa)
• Temperature in Celsius (°C)
• Height above sea level in m (a reference air pressure is required)
