Overview

The MPXV7002DP is a dual-port, integrated silicon pressure sensor designed for measuring positive and negative pressure within a +/-2 kPa range. It provides a high-level analog output signal that is proportional to the applied pressure, making it ideal for microprocessors with A/D inputs. This sensor is specifically engineered for applications requiring differential pressure sensing in low-pressure environments.

Why Choose This Part

The sensor features on-chip signal conditioning and temperature compensation, which simplifies the interface circuitry for the designer. Its dual-port SOP package allows for easy connection to flexible tubing for differential measurements, and it is designed for high sensitivity in the very low pressure range.

Applications

Airspeed Sensing
Used in UAVs and drones with a Pitot tube to calculate airspeed by measuring differential pressure.
HVAC Control
Monitoring filter pressure drops and airflow in duct systems for climate control efficiency.
Medical Respiratory Monitoring
Integrated into ventilators and CPAP machines to monitor patient breathing cycles and gas flow.
Industrial Leak Detection
Detecting small pressure variations in sealed systems to identify pneumatic leaks.

Getting Started

Connect the VCC pin to a stable 5V supply and the GND pin to system ground. The analog output (Vout) can be directly connected to an MCU ADC pin; a simple RC low-pass filter is recommended to reduce noise in high-frequency sampling environments. Refer to the transfer function in the datasheet to convert the voltage output back into kPa or mmH2O units.
