1. Pin Function Specifications and Circuit Principle
The MPXV5010DP is a Differential Pressure Sensor with the following features:
Pin Configuration:The MPXV5010DP has a 5-pin configuration. Below is the description of each pin:
Pin Number Pin Name Pin Function Description Pin 1 Vout (Output Voltage) This is the analog output pin of the sensor that produces a voltage proportional to the measured pressure. Pin 2 Vdd (Supply Voltage) This is the positive Power supply pin. Typically, the supply voltage is 5V. Pin 3 GND (Ground) This is the ground pin for the sensor. It connects to the system's ground. Pin 4 Vref (Reference Voltage) This pin provides the reference voltage to the sensor, typically 5V or 3.3V depending on the application. Pin 5 Reserved Pin used for sensor calibration or additional internal functions.2. Circuit Principle
The MPXV5010DP operates based on a piezo-resistive sensing element. When the sensor is exposed to a pressure difference across its membrane, the piezo-resistive elements in the chip change resistance in response to the applied differential pressure. This change is then converted to an analog output voltage that can be processed by a microcontroller or other external circuitry.
The sensor is typically powered by a 5V DC supply, and the output voltage (Vout) corresponds to the differential pressure applied to the sensor. The output is a ratiometric signal that varies linearly with pressure, providing precise measurement.
