SDP-2000 Senseor

Sorry, I don't English little.

I have a "SDP-2000" Differential-pressure sensors.

SDP-2000 sketch code is make and apple in Arduino

How to Writing arduino Sketch code??

Help the Me Please...

you can use an analog input such as A0
the analog input can sample voltage from 0...5 V Input
the differential pressure sensor sends out 0.25…4.0 V output

so connect 5V on the sdp-2000 to 5V pin on the arduino
Gnd to Gnd
and sdp-2000 out connection to pin A0

the analog input returns an integer values between 0 and 1023
0 being 0 volts and 1023 being 5V

the code depends on which version of the SDP-2000 you have
there are 2 by looking at your datasheet.
Linear output SDP2000-L Formula: P = lfactor * (voltage(1) – 0.250)/3.750
Square Root output SDP2000-R Formula: P = rfactor * (voltage(1) -0.250)^2

voltage can be discovered using this sketch:

/*
  ReadAnalogVoltage
  Reads an analog input on pin 0, converts it to voltage, and prints the result to the serial monitor.
  Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.
 
 This example code is in the public domain.
 */

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
  // read the input on analog pin 0:
  int sensorValue = analogRead(A0);
  // Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V):
  float voltage = sensorValue * (5.0 / 1023.0);
  // print out the value you read:
  Serial.println(voltage);
}

depending on your sensor you will need to add the appropriate math equation to get the exact pressure.

You need to post your project objective. You are asking for code and you haven't even explained what you are trying to do.
Posting general code with nothing specific in mind is a good start if you have nothing and are lost but if expect any help you have to post the following:
1- Outline of Project Objective
2- Any code you might have toward that end.
3- Schematic of any circuit you have related to the project.
4. A STATUS report listing EXACTLY what you have done thus far toward reaching the objective.
If you have done NOTHING, and have NOTHING to show for it, then you need to get started with some tutorials.
5- Ask SPECIFIC QUESTIONS !
6- If you have an English language problem use Google Translate:

7- Pleas for HELP! will not get much attention because that seems to almost be the norm here. Everyone is posting HELP ME
PLEASE ! I AM LOST ! . This will get you nowhere. We ignore that. We have a NO GROVELING policy on the forum. If you want
help, ask politely but don't beg or grovel.. Be professional. If you are on a tight time schedule, it's ok to mention that :

For example:
Hi, I am new. I have a project for school that is due in two weeks and I have not made any progress. Could someone please point me in the right direction ?"

8- Don't ask us to write your code. We are not here to do your homework. I am not trying to be rude but
we get too many requests from students who are too lazy to do their homework and just post here crying for help like they are
dying. Please don't do that . It is very annoying when you have to deal with it day in day out. We are more than willing to give you
guidance and help you find tutorials and debug your code but please don't come right out and ask us to write your code.

You should start by posting an outline of your project and a status report. Any further assistance beyond that will depend on how well you can follow instructions.
