Adafruit BMP280 I2C or SPI Barometric Pressure & Altitude Sensor - STEMMA QT

The BMP280 sensor from Bosch is an advanced environmental sensor designed to measure temperature and barometric pressure, making it an ideal upgrade to the previous BMP085/BMP180/BMP183 models. This next-generation sensor is perfect for various weather sensing applications and offers flexibility with both I2C and SPI communication options.

Key Features:

• Precision Measurement:

  • Barometric pressure accuracy: ±1 hPa.
  • Temperature accuracy: ±1.0°C.
  • Altimeter functionality with ±1 meter accuracy, ideal for altitude measurements.

• Next-Generation Technology:

  • Improved from the BMP085/BMP180/BMP183 with low altitude noise of 0.25m and fast conversion times.
  • Choose I2C for simple wiring or SPI for connecting multiple sensors without address conflicts.

• STEMMA QT Form Factor:

  • The sensor comes mounted on a custom PCB with STEMMA QT connectors, enabling solderless connections with compatible development boards.
  • Compatible with SparkFun Qwiic I2C connectors, making it easy to link to other sensors and accessories.

• Voltage Compatibility:

  • Features a built-in voltage regulator and level shifting, allowing use with both 3.3V and 5V systems (e.g., Metro M4, Arduino Uno).

Easy Integration:

• Pins are broken out to standard headers for convenient wiring.
• Includes a detailed tutorial with wiring diagrams, example code for Arduino and CircuitPython, and resources to get started quickly.

What's Included:

• BMP280 sensor mounted on STEMMA QT PCB.
• QT Cable sold separately (available in the shop).

This precise, low-cost sensor is perfect for your next weather or altitude-related project. Check out the tutorial for wiring, coding examples, and more to get started within minutes!
