BMP280 Barometric Pressure Sensor

The BMP280 is a high-precision, low-power Barometric pressure and temperature sensor from Bosch Sensortec. It is widely used in weather monitoring, altimeter applications, and IoT projects.

Features of BMP280:

• Operating Voltage: 1.71V to 3.6V (Typically 3.3V)
• Interface: I²C (up to 3.4 MHz) and SPI (up to 10 MHz)
• Pressure Range: 300 to 1100 hPa (suitable for altitudes from -500m to 9000m)
• Temperature Range: -40°C to +85°C
• Power Consumption: Ultra-low power (2.7 µA in normal mode)
• Resolution: 0.01 hPa for pressure, 0.01°C for temperature
• Accuracy:
  • Pressure: ±1 hPa
  • Temperature: ±1°C
