hello,
i get a mpx10dp pressure sensor that i need in my project but i am beginner in
electronics so i choice a wrong sensor for me .because it is difficult to wiring .
after some googling i find it need a op amp then the output can connect to arduino
so an one can help me how to wire it ..
sorry for my bad English
thank u
It is a pressure sensor with a bridge inside and nothing else.
The sensor is for 10kPa and has and output is 20mV offset with 35mV full range.
Perhaps an OpAmp like the INA126 can be used, but I didn't find a nice schematic.
Is it possible to buy another sensor ?
Some sensors are compensated and have a linear output of 0...5V.
The pin usage is in the datasheet, figure 1.
1 = GND
2 = +Vout
3 = 5V
4 = -Vout
Also which pin is number 1, is in the datasheet.
