BMP280 Barometric Pressure and Altitude Sensor

This project demonstrates how to interface the BMP280 barometric pressure and altitude sensor module with an Arduino Mega. The BMP280 sensor is capable of measuring atmospheric pressure and temperature, making it suitable for applications requiring environmental monitoring and altitude estimation. By accurately reading pressure and temperature, the sensor allows for precise altitude calculations based on atmospheric pressure variations.
