yess!The sensor outputs a voltage between -0.5V and +0.5V. The Pico can measure voltages between 0V and +3.3V.I'm not sure I understand that, why do we need an offsetting hardware here ?It appears to output between -0.5V and +0.5V so interfacing to an RP2040 ADC will require some kind of offsetting hardware.
What is it ? What does it do ?
So what you need is something that adds 0.5V to the output of the sensor to make it between 0V and 1.0V, and then maybe double that voltage to between 0V and 2.0V so the Pico can read it properly.

is this correct ?
but is it feasible? because I used an ideal op-amp from LTSpice library for simulation.
