MPX10DP Differential Pressure Sensor DocumentationOverviewThe MPX10DP is a high-sensitivity, low-pressure differential pressure sensor that measures the difference in pressure between two ports. It is designed for use in harsh environments and is suitable for applications such as industrial automation, medical devices, and HVAC systems.Technical SpecificationsPressure range: 10 kPa (1.45 psi)
Sensitivity: 1.45 mV/kPa (0.2 mV/psi)
Operating temperature: -40C to 125C
Supply voltage: 5V
Output voltage: 0 to 5V
Response time: 1 msPinoutThe MPX10DP has a 6-pin package with the following pinout:Pin 1: VCC (5V power supply)
Pin 2: GND (ground)
Pin 3: Port 1 (high-pressure input)
Pin 4: Port 2 (low-pressure input)
Pin 5: Output voltage
Pin 6: NC (no connection)Code Examples### Example 1: Basic Pressure Measurement using ArduinoThis example demonstrates how to connect the MPX10DP to an Arduino board and read the pressure difference between the two ports.```c
const int pressurePin = A0; // Analog input pin for pressure measurement
const int pressureThreshold = 200; // Pressure threshold in mV ( approximately 1 kPa)void setup() {
Serial.begin(9600);
}void loop() {
int pressureValue = analogRead(pressurePin);
float pressureVoltage = pressureValue 5.0 / 1023.0;
float pressureDifferential = (pressureVoltage - 2.5) 10.0 / 1.45; // Convert voltage to pressure differential in kPaif (pressureDifferential > pressureThreshold) {
Serial.println("High pressure detected!");
} else {
Serial.println("Low pressure detected!");
}delay(1000);
}
```### Example 2: Pressure Monitoring using Raspberry Pi and PythonThis example demonstrates how to connect the MPX10DP to a Raspberry Pi and use Python to read the pressure difference between the two ports.```python
import RPi.GPIO as GPIO
import timeGPIO.setmode(GPIO.BCM)
pressure_pin = 17 # Analog input pin for pressure measurementdef read_pressure():
GPIO.setup(pressure_pin, GPIO.IN)
pressure_value = GPIO.input(pressure_pin)
pressure_voltage = pressure_value 5.0 / 1023.0
pressure_differential = (pressure_voltage - 2.5) 10.0 / 1.45 # Convert voltage to pressure differential in kPa
return pressure_differentialwhile True:
pressure_differential = read_pressure()
if pressure_differential > 1.0: # Pressure threshold in kPa
print("High pressure detected!")
else:
print("Low pressure detected!")
time.sleep(1)
```### Example 3: Pressure Logging using ESP32 and MicroPythonThis example demonstrates how to connect the MPX10DP to an ESP32 board and use MicroPython to read and log the pressure difference between the two ports.```python
import machine
import timeadc = machine.ADC(machine.Pin(32)) # Analog input pin for pressure measurementdef read_pressure():
pressure_value = adc.read()
pressure_voltage = pressure_value 5.0 / 4095.0
pressure_differential = (pressure_voltage - 2.5) 10.0 / 1.45 # Convert voltage to pressure differential in kPa
return pressure_differentialwhile True:
pressure_differential = read_pressure()
print("Pressure differential: {:.2f} kPa".format(pressure_differential))
time.sleep(1)
```Note: In all examples, the pressure threshold values and voltage ranges are assumed for demonstration purposes only. You should adjust these values according to your specific application requirements.
