NodeMCU ESP8266 I2C Adapter Low Power Issue with SHT31 Sensor LED Glowing Dim

Hello, I am using Node MCU Lolin withI2C adapter for ESP8266 and whenever I am trying to connect my SHT31 sensor with the adapter using I2C cable, while checking the power in sensor  LED glows dimly.First I thought there might be an issue in the sensor so I have changed my sensor and faced the same issue again. Also, the sensor is working perfectly fine with Arduino I2C adapters, I am looking for some advice to avoid this cause, your leads will be a great help. 

Note: I am giving 5v power supply to the Node MCU does It harm Node MCU in any way?

Hi Derby-Are you powering the Node MCU through the micro USB connector? 5 volts should be fine.Is the micro USB connector oriented so it faces the opposite direction from the I2C connector?I suggest disconnecting the SHT31 and then measure the voltage on the GND and +5 volt pins on the I2C connector on the I2C adapter.Can you communicate with the Node MCU through WiFi or USB?-Rick

I went to this link.Can you tell me the reading of the capacitor they are using? If it is using more than 10uF then just bypass it remove this capacitor and solder the open circuit. it will work fineThere is no need of capacitor here. yes, a few nF capacitors can remove the voltage spikes. But using the capacitor that too without any resistance will increase the time constant of the device and can cause delayed charging and discharging.  It's better to bypass this capacitor and try connecting it directly.also as @RickCurl said to check the voltage at Vin pin.

Hi Rick,Yes, I am connecting 5volts supply through micro USB, also USB and the I2C connector is opposite to each while connecting it with the I2C shield.
I just powered up my esp8266 and connected it with and while checking  voltage on the GND and +5 volt pins then the output is around 0.24 v only.

Try disconnecting the ESP8266 from the I2C shield. Then measure the 5 volts on the header pins of the ESP8266.  Did the voltage increase any?

Here  In this shield, they are giving power to I2C device from Vin pin. Whereas, in nodeMCU the vin pin is the input pin for 5v. That's why you are getting just 0.24 v at this pin. So better remove the shield and give the voltage to the sensor form NodeMcu's 3v pin.

If it is using more than 10uF then just bypass it remove this capacitor and solder the open circuit. it will work fine.
