SparkFun Atmospheric Sensor Breakout -
BME280

DESCRIPTION FEATURES DOCUMENTS
The SparkFun BME280 Atmospheric Sensor Breakout is the easy way to
measure barometric pressure, humidity, and temperature readings all without
taking up too much space. Basically, anything you need to know about
atmospheric conditions you can find out from this tiny breakout. The BME280
Breakout has been design to be used in indoor/outdoor navigation, weather
forecasting, home automation, and even personal health and wellness
monitoring.
The on-board BME280 sensor measures atmospheric pressure from 30kPa to
110kPa as well as relative humidity and temperature. The breakout provides a
3.3V SPI interface, a 5V tolerant I C interface (with pull-up resistors to 3.3V),
takes measurements at less than 1mA and idles less than 5µA. The BME280
Breakout board has 10 pins, but no more than six are used at a single time. The
left side of the board provide power, ground, and I C pins. The remaining pins
which provide SPI functionality and have another power and ground, are broken
out on the other side.
Note: The breakout does NOT have headers installed and will need to
purchased and soldered on yourself. Check the Recommended Products
section below for the type of headers we use in the Hookup Guide!

Makes a great accessory to my ESP8266 Thing
about 2 years ago by Member #41996 verified purchaser
The BME280 worked right out of the box and appears to be very accurate. I use it on my weather station and
the readings match the others in my area on the wunderground.com. The pinout of the i2c communications
header is compatible with the ESP8266 Thing so all I had to do was plug it into the socket I had installed on the
Thing, load the SparkFun BME280 Arduino library, and I was up and running.

Great sensor, very easy to hook up and integrate in project!
about 2 years ago by Member #785221 verified purchaser
I had no difficulty wiring the bme280 to my raspberry PI 3. Just used the python libraries to read the sensor.
Highly recommend it!

Reliable, accurate, small
about 2 years ago by MoviesColin verified purchaser
Sensor seems to be fairly accurate, can be used via I2C or SPI, is fairly small, and works reliably. I couldn’t
have asked for more in an atmospheric sensor.

Atmospheric Sensor
about 2 years ago by Member #321089 verified purchaser
By the moment, I do only a little test over this sensor.
Normally Sparkfun gives us good information and examples for Arduino users.
But I normally use PIC16 microcontrollers and do my programs in assembler. Several elements have sufficient
information for me; but others require some reversal engineering from the Arduino examples to discover how to
use it. Then I prepare my programs.
In the future, it is possible to publish some information about the use of the devices without predefined
libraries?

wow! great resolution and works effortlessly
about 2 years ago by Member #336645 verified purchaser
I connected the power and ground and the I2C interfacce. It worked out of the box with my Arduino redboard
using the code I downloaded from the Sparkfun tutorial.
Then I modified the code to take successive readings of the temp, humidity and pressure channels as fast as
possible, average them and print the results ever few seconds.
This dramatically reduced the noise and increased the resolution. I can track 0.1 degC changes, 1 foot
elevation changes and about 0.5% rh changes.

Would have been truely effortless and instantly plug and play if the board came with a ribbon cable soldered in
with pins on the other end to plug into the redboard. I had to take an additional 5 min soldering on the wires.
SparkFun Atmospheric Sensor Breakout - BME280
last year by Member #547716 verified purchaser
Dear,
The sensor that I bought with you, met all my expectations. I’m using it on a Raspberry Pi and it was very easy
to implement this sensor on this board. My next project is to make this sensor work on a PIC16F877A, but from
what I’ve been seeing on the internet, it’s going to be easy to do this implementation.
I take this opportunity to thank you for the cordial service SparkFun has given to me during this purchase.
They are to be congratulated.
Regards,
Reynaldo Silva

last year by free-bee verified purchaser
I bought this to monitor weather data in my bedroom. The hookup guide wasn’t too clear to me on how to get
data from it (it was there, just not where I was expecting it) but I eventually got what I needed from it. I put it up
against a digital thermostat–not physically–and the two read very close to the same temperature and humidity.
