Thank you very much. Is there another solution possible because in my project i need to use 2 BME280 boards. so I2C won't be much of a solution.

most i2c devices will support more than 1 address, usually with a couple of pads on the board, connecting or breaking connections can change the address, so then you would be able to use 2 sensors on i2c

The BME280 supports two I2C slave addresses by tying SDO to either GND or Vddio. If you need to connect more than 2 devices to the same master use an I2C multiplexer as the PCA9547.
