BMP280 Digital Barometer Pressure Sensor Module

A very compact barometer that works via I2C or SPI. The BMP280 is the better successor to the BMP180 with buildin temperature sensor and pressure sensor.

For more information see the datasheet under the tab "Downloads".

The module can only be fed with 3.3VDC. The I2C/SPI also works with 3.3V and you need a level converter with use of eg. a 5V Arduino Uno.

The standard I2C address of this module is 0x76. This may need to be changed from 0x77 to 0x76 in the example code / library. If you connect the SDO pin with Vcc, then the I2C address becomes 0x77.

Note: Due to the many chip shortages, it is possible that this product uses a refurbished (genuine) BMP280 sensor.
