This is a cheap yet ubiquitous pressure sensor based om a Wheatstone bridge. Unlike the MIS-2500, it requires amplification using an Op-Amp.

After plenty of reading and experimenting I came up with the following LM358 based circuit that I am satisfied with.

This pin diagram is for the version of the sensor that I ordered.

The circuits I have seen online use two connections to the LM358, first as a differential amplifier and then as a normal amplifier. I believe that I can manage with just differential amplification, because it provides both amplification to the signal and eliminating the 2.5v offset of the output.

*Based on the image in “The answer is 42”

* I also added 100Uf capacitors because seems like that was recommended.
