@BMAnush , if the I2C address scanner finds your BME280 at its defined address then the wiring should be OK. I have used this device with an ESP8266-12E and it works flawlessly even with several other sensors on the same I2C bus at different addresses. You don't say which library you are using but I would suggest using an Adafruit library and their basic example as a starting point. Also check you are powering the sensor correctly.
