Types of Pressure Sensors

1. Absolute Pressure Sensors – Measure pressure relative to a perfect vacuum (0 Pa).
2. Gauge Pressure Sensors – Measure pressure relative to atmospheric pressure (e.g., tire pressure).
3. Differential Pressure Sensors – Measure the difference between two pressure points (e.g., airflow measurement).

Working Principle

Most pressure sensors operate using one of the following principles:

• Strain Gauge – Converts pressure-induced strain into an electrical resistance change.
• Capacitive – Measures pressure by detecting changes in capacitance due to diaphragm displacement.
• Piezoelectric – Generates a voltage when subjected to pressure.
• Optical – Uses light variations due to pressure changes.

Applications

• Automotive – Tire pressure monitoring, fuel injection systems.
• Industrial – Hydraulic and pneumatic systems.
• Medical – Blood pressure monitors, respiratory equipment.
• Consumer Electronics – Smartphones (barometers), wearable devices.

MPX5010DP Sensor:-

The MPX5010DP is a differential/gauge pressure sensor from NXP (formerly Freescale). It is designed to measure low-pressure values and output a proportional analog voltage signal.

Key Features of MPX5010DP

• Pressure Range: 0 to 10 kPa (0 to 1.45 psi)
• Type: Differential/Gauge Pressure Sensor
• Output: 0.2V to 4.7V Analog Voltage (proportional to pressure)
• Supply Voltage: 4.75V to 5.25V
• Accuracy: ±5% full-scale

2. Working Principle

The MPX5010DP operates using piezoelectric pressure sensing technology, where a thin silicon diaphragm flexes under pressure. The strain in the diaphragm causes changes in electrical resistance, which are converted into an analog voltage output proportional to the applied pressure.

• Gauge Mode: Measures pressure relative to atmospheric pressure. One port is open to the environment.
• Differential Mode: Measures the pressure difference between the two ports.

Output Voltage vs. Pressure Relationship

• The output voltage is linearly proportional to the applied pressure.
• Formula: Vout=Voffset+(Sensitivity×P)V_{\text{out}} = V_{\text{offset}} + (Sensitivity \times P)Vout​=Voffset​+(Sensitivity×P) Where:
  • Voffset=0.2VV_{\text{offset}} = 0.2VVoffset​=0.2V (when no pressure is applied)
  • Sensitivity = 450 mV/kPa
  • $P$ = Applied Pressure in kPa

Example:

• At 0 kPa, output ≈ 0.2V
• At 5 kPa, output ≈ 2.45V
• At 10 kPa, output ≈ 4.7V
