BMP280 Breakout – Temperature, Pressure, Altitude Sensor Pimoroni

DESCRIPTION

A fast and precise environmental sensor that can measure temperature, pressure, and altitude. This BMP280 breakout is Raspberry Pi and Arduino-compatible.

If you’re looking for a simple temperature and pressure sensor, then this is the one to pick. It’s cheap and accurate (±1 hPa, ±1.0°C, ±1 metre), and ideal for keeping track of temperatures around your home or even for measuring altitude in high-altitude balloon flights.

Please Note:

• The software does not support Raspbian Wheezy.
• The solder pads (marked ADDR) can be bridged to change the I2C address from the default of 0x76 to 0x77, meaning that you can use up to two sensors on the same Raspberry Pi or Arduino
• The BME680 and BMP280 breakouts both share the same I2C addresses, so if you’re using both together then you’ll need to change the I2C address on one of them using the solder bridge/pads

FEATURES

• Bosch BMP280 temperature, pressure, altitude sensor
• I2C interface, with address selected via ADDR cuttable trace (0x76 or 0x77)
• 3.3V or 5V compatible
• Reverse polarity protection
• Raspberry Pi-compatible pinout (pins 1, 3, 5, 7, 9)
• Compatible with Raspberry Pi 3B+, 3, 2, B+, A+, Zero, and Zero W
• Python library available
• Dimensions: 19x19x2.75mm (LxWxH)

Kit includes

• BMP280 breakout
• 1×5 male header
• 1×5 female right angle header

They’ve designed this breakout board so that you can solder on the piece of right angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi’s GPIO header (pins 1, 3, 5, 6, 9). The right angle header also has the advantage of positioning the breakout away from the Pi’s CPU so as to minimise radiated heat.

RESOURCES

The Python library for the BMP280 makes it simple to take readings from the sensor.
