SDP-2000 Senseor

sorry, don't english little.

i have "sdp-2000" differential-pressure sensors.

sdp-2000 sketch code make , apple in arduino

how writing arduino sketch code??

help me please...

you can use analog input such a0
the analog input can sample voltage 0...5 v input
the differential pressure sensor  sends out 0.25…4.0 v output

so connect 5v on sdp-2000 5v pin on arduino
gnd gnd
and  sdp-2000 out connection pin a0

the analog input returns integer values between 0 , 1023
0 being 0 volts , 1023 being 5v

the code depends on version of sdp-2000 have
there 2 looking @ 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 discovered using  this sketch:

code: [select]

/*
 readanalogvoltage
 reads analog input on pin 0, converts voltage, , prints result serial monitor.
 attach center pin of potentiometer pin a0, , outside pins +5v , ground.

example code in public domain.
*/

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

// loop routine runs on , on again forever:
void loop() {
 // read input on analog pin 0:
 int sensorvalue = analogread(a0);
 // convert analog reading (which goes 0 - 1023) voltage (0 - 5v):
 float voltage = sensorvalue * (5.0 / 1023.0);
 // print out value read:
 serial.println(voltage);
}


depending on sensor need add appropriate math equation exact pressure.
