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).
