Understanding the Gravity Analog AC Current Sensor

Hi everyone,


I am not able to understand what is the auxilliary AC Current Signal Conversion Module board is doing with the CT transfomer.


Would some one explain?


I am interested in collecting the raw current sine wave values from the transformer, and it seems impossible to do that.


Is the conversion module is stoping me from doing so?


Thank you very much for your help,

Can anyone help me please, I am trying to read the Current Sensor with a ESP32  but only reads 0,  an amperimeter reads .640 amp.  Thanks

Please notice that the Gravity: Analog AC Current Sensor(SKU:SEN0287) is used to measure the AC current only. while it is an analogue output device only, the output of the current will change if the voltage change.

Could you please low down the frequency of your sine wave and shorten the delay time in Arduino?

Hope it can help.
