Detailed Description:

The BMP280 is a next-generation barometric pressure and altitude sensor designed by Bosch, offering excellent accuracy and energy efficiency for both indoor and outdoor applications. It supports both I2C and SPI communication, making it compatible with a wide range of development boards including Arduino, ESP32, NodeMCU, and Raspberry Pi.

The BMP280 measures absolute pressure and uses that data to determine altitude, making it perfect for weather forecasting, elevation detection, or drone height stabilization. It features a compact PCB with onboard level shifters and pull-up resistors for direct microcontroller integration.

Key Features:

• High precision barometric pressure sensing

• Measures altitude, pressure, and temperature

• Supports both I2C and SPI interfaces

• Wide operating voltage: 1.8V to 3.6V

• Low power consumption – ideal for battery-powered devices

• Compact size for embedded applications

• Fully calibrated digital output

• Compatible with Arduino, ESP8266, ESP32, Raspberry Pi, STM32

Technical Specifications:

How to Use:

1. Connect VCC, GND, SCL, SDA (I2C) to your controller

2. Alternatively, use SPI pins: SCK, SDI, SDO, CS

3. Use libraries like Adafruit BMP280, SparkFun BMP280, or Bosch BMP280 drivers

4. Retrieve barometric pressure, altitude, and temperature data

5. Calibrate based on sea level pressure if high accuracy is needed
