bme 280 and nodemcu lolin v3 no readings

Hello,

I am trying to make a weather station and air quality monitor using the bme 280 sensor and nova sds011 .After flashing the nodemcu, i proceeded in wiring the sensor.VCC to 3v,GND to G,Sda to pin d3 and Scl to pin D4.In the debug menu i get the following :

Read bmp280/bme280

Trying bmp280-bme280 sensor on 76......not found

Trying bmp280-bme280 sensor on 77......not found

Check bmp280-bme280 wiring

In other times it shows sensor found but when it comes to displaying the data it does not show the measurements.

I even reflashed the board with an older version.Still i have the same problem.

What could be the cause?

thanks in advance
