Hello Sir,
I am new in the community. I need some help for my circuit.
I am using LM358 for building diff.amplr circuit for making sensor offset zero.
But, its not working properly. Offset of my sensor is 100mv. Can you please help me to build the circuit?
Thank you.

You don't give much information. Please post your circuit including the transducer.

By the way the LM358's output cannot go all the way ground unless you help it with a 2.2k resistor (typical value) from the output to ground.
