Description

Hello all,
![image](https://user-images.githubusercontent.com/43772343/135480270-cc7c8550-0835-4b8b-a46f-c16fbe6214a6.png)

I am having nearly 10 - SCD_30 Sensors for measuring CO2 Value, Temperature, and Humidity for an project.

I was recording succesfully all the values without any problems making simple circuit with rapsberrypi:
Vcc,grnd, SDA, SCL and SEL.
Suddenly i am getting value of `0.0` for CO2 alone. i am not sure why its happening. But works fine with different sensor with same rapsberry and same code.

I need an help, :(
0.0 value is mentioned (@ End of the image)

Research direction

Start by reproducing the reported setup with the Raspberry Pi, the Vcc, ground, SDA, SCL, and SEL connections, and the same code. Compare the affected SCD30 with a working sensor and verify whether only CO2 returns 0.0; done means identifying a reproducible library or hardware cause and documenting the evidence.
