For a wheatstone bridge output (two pins) you need a instrumentation amplifier.
Some Arduino boards or external ADC's have a differential mode with a gain. That is the same as the instrumentation amplifier.
Sometimes it is possible to connect them directly to a Arduino board to get a rough indication of the pressure. Then you know if it is working.
Can you tell which pressure sensor it is ?
What is your project ? We like to have a broader view.
Which Arduino board do you use ? If you use a ESP8266 or ESP32, then it will not be accurate.
There are pressure sensors that output 0.5 to 4.5V, they go well with a 5V Arduino board. Those are also available in 3.3V versions.
That sensor will probably work with 5V as well. I think it will work also with 3.3V and probably with a lower voltage. For example the 2.5V from a INA125.
So that sensor with a INA125 instrumentation amplifier should work.
I think there is only a wheatstone bridge inside that sensor.
The challenge with many single-power-rail op-amps is that they cannot drive the output that close to the power rails. Especially towards the GND line.
Usually, if you can get to 0.7 v of the rail you are lucky.
However, you can buy "rail-to-rail" Op-Amps which can get very close to the power rail levels.
So, they key thing to look for in this case is how close the op-amp output will drive to 0V.
Now.... if you use an Op Amp with both + and - power rails (like +-12V) that is s better way to do. In this case any standard op-amp should do. Even the humble 741.
If you do that you need to remember to protect the microcontroller from being fried by the opamp output - 10k resistor to limit current for instance.
These days there are plenty of rail-to-rail 5V capable opamps out there for interfacing to microcontrollers, Microchip have a large range I believe, checkout
for instance the MCP6002.
But all this is immaterial because you have a strain-gauge sensor which immediately
suggests using an instrumentation amp, and the HX711 is pretty-much the "go to"
device for this in the Arduino world, lots of examples out there to copy.
The sensor can be powered (excitation) with max 10volt, but that doesn't mean it won't work with a lower voltage. HX711 boards have a ~4.3volt excitation voltage, which is perfectly fine.
4.3volt excitation means that you must power the HX711 board with 5volt.
But... if you use a 3.3volt processor, you can only use a HX711 board with two supply connections.
A 5volt supply for the sensor part of the HX711 (VCC), and 3.3volt supply for the logic part of the HX711 (VDD). Only Sparkfun sells boards like that. Or modify a common board yourself if you can.
