Barometric Pressure Circuit Diagram In this tutorial we will use the Adafruit BMP280 sensor. This sensor can measure barometric pressure and temperature with very good accuracy. Because pressure changes with altitude we can also use it as an altimeter with ±1 meter accuracy! Accuracy for barometric pressure is ±1 hPa and ±1.0°C for temperature.
How high are you right now? If you had a precision altitude sensor, you would know for sure! The DPS310 sensor from Infineon a high precision barometric sensor, perfect for measuring altitude changes with a up to ±0.002 hPa (or ±0.02 m) precision high precision mode and ± 1 hPa absolute accuracy. You can know your absolute altitude with 1 meter accuracy when you set the sea-level pressure

The Adafruit DPS310 is a precision sensor capable of measuring barometric pressure and altitude with high accuracy. It communicates via I2C or SPI digital interface, making it compatible with a wide range of microcontrollers, including Arduino and Raspberry Pi. This variable saves the pressure at the sea level in hectopascal (is equivalent to milibar). This variable is used to estimate the altitude for a given pressure by comparing it with the sea level pressure. This example uses the default value, but for more accurate results, replace the value with the current sea level pressure at your location. I2C
