HiLetgo 3pcs ESP8266 NodeMCU CP2102 ESP-12E Development Board Open Source Serial Module Works Great for Arduino IDE/Micropython (Large)

Adafruit BME280 I2C or SPI Temperature Humidity Pressure Sensor

BME680 I2C
To use I2C communication protocol, use the following pins as per the
ESP8266 NodeMCU: BME680 Environmental Sensor using tutorial

BME680 ESP8266
SCL GPIO 5 (D1)
SDA GPIO 4 (D2)

Hi.
Are you sure you’re wiring it correctly?
I searched for the pinout of that sensor, and the SCL pin is labeled as SCK and the SDA pin is labeled as SDI.
What about power? How are you powering the sensor?
Use this I2C scanner sketch to find out if the board is able to find the sensor with I2C protocol:
