## Description

The BMP280 from Bosch is a precision barometric pressure and temperature sensor, and the next-generation upgrade to the BMP085/BMP180/BMP183 family. With support for both I2C and SPI communication, it offers flexibility for a wide range of weather sensing and altitude estimation projects. With ±1 hPa barometric pressure accuracy and low altitude noise of 0.25 metres, the BMP280 delivers reliable environmental readings suitable for weather stations, altimeters, and IoT applications. The breakout board includes a 3.3V regulator and level shifting for easy use with both 3V and 5V microcontrollers. Key Features Barometric Pressure – ±1 hPa absolute accuracy Temperature – ±1.0°C accuracy Altimeter – ±1 metre accuracy with 0.25 m noise floor Dual Interface – I2C and SPI communication Voltage Range – 3–5V operation via onboard regulator and level shifting Fast Conversion – Quick sampling for responsive applications Also Available Adafruit BMP280 – Assembled – Same sensor with headers pre-soldered Adafruit BMP388 – Higher precision altimeter (±0.5 m accuracy) Adafruit BME280 – Adds humidity sensing to pressure and temperature Adafruit BME680 – Adds humidity and VOC gas sensing Ideal For Weather stations and environmental monitoring Altitude estimation for drones and robotics IoT environmental sensing projects Multi-sensor setups using SPI to avoid I2C address conflicts Package Contents 1× Adafruit BMP280 breakout board (headers not soldered)
