  • Raspberry Pi

    The Raspberry Pi Foundation works to put the power of digital making into the hands of people all over the world, so they are capable of understanding and shaping our increasingly digital world, able to solve the problems that matter to them, and equipped for the jobs of the future. We provide low-cost, high-performance computers that people use to learn, solve problems and have fun. We provide outreach and education to help more people access computing and digital making. We develop free resources to help people learn about computing and how to make things with computers, and train educators who can guide other people to learn.

    Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can
    even be used in both I2C and SPI!

    This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy.
    Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy
    The BME280 is the next-generation of sensors from Bosch, and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time.
    It has the same specifications, but can use either I2C or SPI. For simple easy wiring, go with I2C.
    If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.
    Nice sensor right? So we made it easy for you to get right into your next project.
    The surface-mount sensor is soldered onto a PCB and comes with a 3.3V regulator and level
    Shifting so you can use it with a 3V or 5V logic microcontroller without worry.
    We even wrote up a nice tutorial with wiring diagrams, schematics, libraries and examples
    to get you running in 10 minutes!
    Power Pins:

    Vin - this is the power pin. Since the sensor chip uses 3 VDC, we have included a voltage regulator on board that will take 3-5VDC and safely convert it down. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V
    3Vo - this is the 3.3V output from the voltage regulator, you can grab up to 100mA from this if you like
    GND - common ground for power and logic

    SPI Logic pins:

    All pins going into the breakout have level shifting circuitry to make them 3-5V logic level safe. Use whatever logic level is on Vin!

    SCK - This is the SPI Clock pin, its an input to the chip
    SDO - this is the Serial Data Out / Master In Slave Out pin, for data sent from the BMP183 to your processor
    SDI - this is the Serial Data In / Master Out Slave In pin, for data sent from your processor to the BME280
    CS - this is the Chip Select pin, drop it low to start an SPI transaction. Its an input to the chip

    If you want to connect multiple BME280's to one microcontroller, have them share the SDI, SDO and SCK pins. Then assign each one a unique CS pin.

    I2C Logic pins:

    SCK - this is also the I2C clock pin, connect to your microcontrollers I2C clock line.
    SDI - this is also the I2C data pin, connect to your microcontrollers I2C data line.

    Leave the other pins disconnected
