MPS20N0040D #6179

4211421036 · 2025-04-10T10:05:17Z

MPS20N0040D

Scientific Background

1. Pressure Measurement Principle

The sensor uses MEMS piezoresistive technology. The output voltage ($V_{out}$) relates to applied pressure ($P$) by:

$$ V_{out} = V_{bias} + S \cdot P + \epsilon(T) $$

Where:

$S$ = Sensitivity (-0.21%FS/°C, datasheet)
$\epsilon(T)$ = Temperature error (±0.08%FS/°C)

2. Venturi Flow Equation

Flow rate ($Q$) is calculated using Bernoulli's principle:

$$ Q = A_1 \sqrt{\frac{2\Delta P}{\rho(1-\beta^4)}} $$

Where:

$\beta = \frac{d_2}{d_1}$ (diameter ratio)
$\rho$ = Fluid density (kg/m³)

Wiring Diagram

The following is a description of the image:

The sensor, designated as MPS20N0040D-S, is connected to
- Pin 1, identified as V+. It is to be connected to a 5V Microcontroller
- Pin 2 (GND) is to be connected to: Connects to GND Microcontroller
- Pin 3 (Vout+): Connects to IN+ HX710
- Pin 4 (Vout-): Connects to IN- HX710

Installation

Download the ZIP and install via Arduino IDE:
Sketch > Include Library > Add .ZIP Library

Or clone to Arduino libraries folder:

git clone https://github.com/yourusername/MPS20N0040D.git

Function Documentation

Function	Parameters	Description
`begin()`	-	Initializes sensor and ADC pins
`readPressure()`	-	Returns pressure in Pascals (Pa)
`calculateFlowRate()`	`pressureDiff`, `density` (optional)	Computes flow rate in m³/s

Example Code

#include <MPS20N0040D.h>

// Pin definition
#define PD_SCK 3
#define DOUT 4

MPS20N0040D sensor(PD_SCK, DOUT);

void setup() {
  Serial.begin(9600);
  sensor.begin();
}

void loop() {
  float pressure = sensor.readPressure();
  float flowRate = sensor.calculateFlowRate(pressure, 1000.0); // Water density
  
  Serial.print("Pressure: "); 
  Serial.print(pressure); 
  Serial.println(" Pa");
  
  Serial.print("Flow Rate: "); 
  Serial.print(flowRate * 1000, 2); // Convert to L/s
  Serial.println(" L/s");
  
  delay(1000);
}

Calibration Procedure

Apply known pressures (0-40kPa) using a dead weight tester
Record ADC outputs

Update these constants in MPS20N0040D.cpp:

const float V_REF = 5.0;    // Measured reference voltage
const float FS_OUTPUT = 0.1; // Verified full-scale output

Technical Specifications

Parameter	Value	Unit
Pressure Range	0-40	kPa
Accuracy	±0.25	% FS
Operating Voltage	2.6-5.5	V
Output Data Rate	10/80	SPS

@4211421036 you are establishing a clear pattern of making this mistake in your pull requests. I already explained to you what you need to do:

#5984 (review)

Make sure to always create a branch in your fork for each pull request. You should never make any commits directly to the main branch in your fork. The main branch should always match the main branch in this repository exactly. This way, you can use the main branch as the base for the branches you create for your pull requests. You can learn how to do that from this tutorial:

https://docs.github.com/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request-from-a-fork

Always make sure the main branch in your fork is in sync with the main branch in this repository before you make the branch for your pull request. You can learn how to sync your fork from the documentation here:

https://docs.github.com/pull-requests/collaborating-with-pull-requests/working-with-forks/syncing-a-fork

Did you read what I wrote? If not, then please start paying better attention! If you did read it, then why did you make the same mistake yet again?

This is a basic skill for anyone doing software development on GitHub, which you would need for any pull requests not only for contributions to this repository. If these libraries are actually your own work and not just AI-generated slop, then clearly you are highly intelligent and competent, so surely you are capable of understanding the basics of working with GitHub forks and pull requests.

Hi @4211421036. I am rejecting your submission. Although we try to make creating Arduino projects accessible to everyone, the situation is different when it comes to publishing libraries to the Arduino Library Manager. We expect a high level of competence from the maintainers of libraries published to Library Manager and your actions in this pull request and previous pull requests show that you don't meet our standards.

This is the third pull request in which you made this mistake.

The first time, I simply cleaned up your mess for you:

#5960 (comment)

The second time, I also cleaned up your mess for you, and provided detailed advice as to how to correctly use GitHub pull requests

I gave you advice about how you could easily overcome this difficulty multiple times:

#5984 (review)

But now here you are back again making the same mistakes as always. I repeated my advice:

#6179 (review)

but you simply ignored me and instead wasted your time and my time endlessly pushing pointless commits to the pull request.

You have also established a pattern of unnecessarily submitting duplicate pull requests:

⚠ Repeated irresponsible behavior will result in the revocation of your Library Manager Registry privileges. This is your last warning!

Thanks in advance for your cooperation.
