MPXV5010G6U 概要
A piezoresistive pressure sensor is a MEMS device in which a micromachined silicon diaphragm flexes under applied pressure, changing the resistance of embedded strain gauges arranged in a Wheatstone bridge. The on-chip ASIC then amplifies, calibrates, and temperature-compensates the bridge output to deliver a near-linear voltage proportional to pressure. These devices sit in a measurement hierarchy of absolute, gauge, differential, and vented-gauge types and are widely used where a microcontroller or ADC can read the analog output directly.
Key features include a 5 % maximum pressure error (over 0–80 °C), a typical response time of 1 ms, and a 10 kPa full-scale range that resolves about 2.3 mV per Pa through the 0.2 V–4.7 V output swing. The 8-SMD small-outline package includes a vertical pressure port, and the vented-gauge reference lets the device track atmospheric pressure changes without operator intervention. Ratiometric output ensures accuracy tracks the ADC reference, simplifying system calibration.
Typical applications include ventilator and respiratory airflow monitoring, HVAC variable-air-volume (VAV) box control, industrial process pneumatic monitoring, altitude and barometric sensing for portable instruments, and weather-station front ends. The compact 8-SMD footprint supports space-constrained designs such as handheld patient monitors and IoT environmental nodes.
When designing in, place 100 nF and 470 pF supply decoupling close to the Vs and GND pins, and follow the manufacturer reference PCB layout to minimize stress on the silicon die. Ratiometric operation requires the ADC reference to share the same 5 V rail as the sensor for specified accuracy.

主な用途
MPXV5010G6U の用途: 6 件s: Ventilator and Respiratory Airflow Monitoring, HVAC Variable Air Volume (VAV) Box Control, Industrial Process Pneumatic Monitoring, Barometric and Altitude Sensing, Weather Station Front End, Portable Environmental IoT Nodes.
Ventilator and Respiratory Airflow Monitoring
The MPXV5010G6U is widely deployed in ventilator airflow and respiratory-pressure circuits: the 0–10 kPa range maps directly to typical patient airway pressures (100 mm H₂O ≈ 1 kPa), the 1 ms response time accurately tracks breath cycles, and the ±5 % accuracy is sufficient for patient-side sensing. The 0.2 V–4.7 V ratiometric output drives a 10-bit or 12-bit MCU ADC directly without instrumentation amplifiers, reducing BOM cost. NXP application note AN3956 demonstrates MPXV5010-series use in differential flow sensing across a flow restriction element. The vented-gauge reference automatically compensates for ambient barometric pressure changes, which is critical when patients are moved between altitudes. The 8-SMD package fits compact handheld or bedside patient monitors.

HVAC Variable Air Volume (VAV) Box Control
The MPXV5010G6U is purpose-built for HVAC variable-air-volume (VAV) box control: the 0–10 kPa range covers typical duct static-pressure setpoints (0.1–1 kPa), the 0.2 V–4.7 V analog output drives a 10-bit MCU ADC without signal conditioning, and the vented-gauge reference automatically compensates for atmospheric pressure variations that would otherwise drift the control loop. Unlike absolute-pressure sensors, the vented-gauge topology eliminates the need for software altitude correction across multi-story buildings. The 8-SMD SMD form factor simplifies high-volume SMT assembly compared to legacy through-hole MPX-series sensors, and the 5 V single-rail operation simplifies power-tree design in 24 VAC-powered thermostat units.
おすすめ
Industrial Process Pneumatic Monitoring
The MPXV5010G6U monitors low-pressure pneumatic lines in industrial automation: 0–10 kPa covers vacuum-pad hold pressure and small pneumatic actuator feedback, the on-chip temperature compensation removes drift across factory floor temperature cycles (0 °C to 85 °C), and the ratiometric output tracks the 5 V ADC reference for stable absolute readings. The 8-SMD SO package withstands typical SMT reflow profiles (per J-STD-020) and supports high-density PCB layouts common in PLC and distributed I/O modules. The 1 ms response time enables closed-loop pressure control faster than the typical pneumatic actuator response, ensuring the sensor is not the bandwidth bottleneck.
おすすめ
Barometric and Altitude Sensing
The MPXV5010G6U can be configured for barometric and altitude sensing when paired with an absolute-pressure variant: the 0–10 kPa range maps to roughly 0–800 m of altitude change above sea level. The vented-gauge reference (open to atmosphere through the package port) means the output reflects only differential pressure vs ambient, which is precisely what altitude-aware HVAC and weather-station applications require. The factory calibration delivers ±5 % accuracy without user trimming, simplifying firmware. The 5 V single-supply operation matches typical weather-station and GPS data-logger power trees.
おすすめ
Weather Station Front End
The MPXV5010G6U functions as the differential-pressure front end in low-cost weather stations when paired with a Pitot tube or differential pressure pickup: the 0–10 kPa range covers typical wind-speed-derived pressures, and the ratiometric 0.2 V–4.7 V output drives a 10-bit MCU ADC directly. The on-chip temperature compensation (0 °C to 85 °C) eliminates the thermocouple or RTD corrections that a discrete bridge would require. The 8-SMD SMD package supports weather-resistant conformal-coated assemblies, and the 5 V supply matches typical solar-powered weather-station power systems with linear regulation.
おすすめ
Portable Environmental IoT Nodes
The MPXV5010G6U supports space-constrained portable IoT environmental nodes: the 0–10 kPa range suits low-differential-pressure sensing (e.g., air-quality enclosure leak detection), the 8-SMD SO package fits sub-100 mm² sensor boards, and the analog output lets a low-power MCU with ADC (e.g., a Cortex-M0+) read pressure directly without dedicated signal conditioning. The ratiometric output enables the MCU ADC reference to share the same 5 V rail, removing a precision component. The 1 ms response time is more than adequate for environmental sampling rates of 1 Hz or below, allowing the host MCU to duty-cycle the ADC for battery-life extension.

設計ノート
The MPXV5010G6U requires a clean 5 V supply (4.75 V to 5.25 V). Place a 100 nF ceramic decoupling capacitor as close as possible to the VS pin and a 470 pF high-frequency bypass across VS and GND. A linear regulator (e.g., LM7805 or LDO) is preferred over a switching regulator to avoid switching noise coupling into the analog Vout signal. Ratiometric operation requires the ADC reference voltage to share the same 5 V rail as the sensor for specified accuracy.
Follow the manufacturer reference PCB layout closely. Do not place components or route signal traces directly under the sensor package; the silicone gel over the die must not be mechanically stressed. Keep the package port clear of obstructions and provide at least 4 mm clearance around the port for tubing attachment. Use a single solid ground plane under the analog section, and route Vout away from switching nodes or high-current traces to minimize coupled noise.
Use an ADC input RC filter (typ. 1 kΩ + 100 nF) on Vout to limit broadband noise and aliasing. The 1 ms response time of the sensor sets an upper bandwidth of about 160 Hz (fc ≈ 0.35/tr), so a higher-order anti-alias filter is unnecessary. Add a software averaging filter (4 to 16 samples) to improve effective resolution by 1 to 2 ENOBITS without sacrificing response time for typical environmental sampling.
