Hi guys
I need your help to making work the pressure sensor MPS20N0040D (module with hx7110) , I uploaded the sketch , but I can't get a right graphic , it's seems to be not fonctional !!!
It's the same graphe with & without the module connected
To the arduino !!!
Please help
Best regards
You failed to post the code you used for this, you failed to post a wiring diagram of your setup, you failed to post a link to the used hardware. Did you actually read the sticky post at the top of the forum ("How to use the forum")?
You probably made an error, it might be in the circuit, in the code or in the choice of components. We haven't the slightest chance to know because you're hiding all relevant information from us.
Oh I am sorry it's my first post about the sensor
The sketch :
/*
Pressure Sensor test Code
*/
const int analogInPin = A0; // Sensor connected to A0
int sensorValue = 0; // value read from the pressure sensor via the amplifier stage
float outputValue = 0; // value output to the Serial port
void setup() {
// initialize serial communications at 9600 bps:
Serial.begin(9600);
}
void loop() {
// read the analog in value:
sensorValue = analogRead(analogInPin);
// print the results to the serial monitor:
Serial.print("sensor = " );
Serial.print(sensorValue);
Serial.println();
delay(1000);
}
Arduino Uno + the pressure sensor (module MPS20N0040D)
The diagram gnd-gnd
Vcc-5v
Sck A0
Out A1
You still didn't read the sticky post. Edit your post and insert code tags!
Still no links to the used hardware.
Your board seems to use the mentioned sensor together with the HX711. The HX711 has a digital output so you cannot get a value from it by reading a value from the Arduino ADC.
There are many tutorials about how to read from the HX711 (although most of them are for weight sensors but your pressure sensor works almost identically). Use Google to choose one that fits your needs.
