This is a breakout board with a Bosch BME-280 combined temperature and barometric pressure sensor, mounted with all components necessary to connect to a Arduino, Pi, ESP8266 or other micro-controler via a simple I2C interface. Hookup is simple, and standard libraries are available online. The board is tiny, yet very capable and easy to use. This can be powered from and connected to either 3.3V or 5V devices without modification.
Orders received before 2pm on normal weekdays will be posted the same day. Orders received later or on public holidays/weekends will be posted the next business day.

We recommend the use of the "Sparkfun BME-280" library for this sensor (it works well for both BMP-280 and BME-280 boards, though humidity data will only be valid with the BME-280)
This is an optional library in the Arduino IDE, simply search in the Library Manager and install directly. Both the Adafruit and Sparkfun libraries default to I2C address 0x77, however these devices have I2C address 0x76. With the Sparkfun library this is specified in the example sketches so is easily changed - where the Adafruit library hard codes the address, so the library header files have to be edited.
