MPX5010GP - 0-10kPa Vented Gauge Pressure Sensor | NXP
MPN: MPX5010GP ✗ Cuối đờiMPX5010GP Tóm tắt
What is a gauge pressure sensor? A gauge pressure sensor measures pressure referenced to ambient atmospheric pressure through a vent port, distinguishing it from absolute sensors (which reference a sealed vacuum) and differential sensors (which measure between two ports). Within the broader sensor hierarchy, the MPX5010GP sits as a pressure transducer in the sensors category, where piezoresistive MEMS technology dominates low-pressure applications due to its high sensitivity, small size, and CMOS-compatible signal conditioning.
Key features include on-chip signal conditioning that eliminates the need for external amplification, factory calibration that reduces part-to-part variation to approximately ±1.5% per the datasheet, and integrated temperature compensation from 0 °C to 85 °C. The 0.2 V to 4.7 V ratiometric output is referenced to the 5 V supply, ensuring noise immunity and accurate conversion when paired with a 5 V ADC reference.
The sensor combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing on a single monolithic die. A piezoresistive bridge etched into the silicon diaphragm converts mechanical strain into a millivolt-level differential signal, which the on-chip ASIC amplifies, calibrates, and linearizes to produce the final analog output with minimal user-side conditioning.
Typical applications include medical respiratory monitoring such as CPAP and spirometry, HVAC differential pressure sensing, industrial process control, vacuum cleaner and appliance load sensing, and altitude estimation in drones and portable instruments. The combination of low-pressure sensitivity and analog ratiometric output makes the MPX5010GP especially useful where ADC integration is straightforward and battery life is not the primary constraint.
When designing with this part, take care to mount the SIP package vertically on the PCB so the port faces downward or sideways, matching the recommended manifold geometry in the datasheet to avoid pressure measurement errors caused by port orientation. Decouple the 5 V supply with a 100 nF ceramic capacitor placed close to the sensor supply pin to suppress switching noise from downstream digital circuitry.

Ứng dụng tiêu biểu
MPX5010GP phù hợp cho 6 Áp dụngs: Medical Respiratory Monitoring (CPAP / Spirometry), HVAC Differential / Static Pressure Sensing, Industrial Vacuum and Process Control, Consumer Appliance Load / Vacuum Sensing, Drone and Portable Altitude Estimation, Blood Pressure Monitor Air-Pressure Sensing.
Medical Respiratory Monitoring (CPAP / Spirometry)
The MPX5010GP's 0 to 10 kPa range aligns precisely with the breath-pressure envelope encountered in CPAP machines, spirometers, and ventilator circuit monitoring, where pressures typically span 0.5 to 6 kPa during normal respiration. Its ratiometric analog output spanning 0.2 V to 4.7 V connects directly to a 5 V medical-grade ADC, preserving calibration accuracy when the supply drifts by ±2.5%. The on-chip temperature compensation from 0 °C to 85 °C maintains sensor accuracy across the warm-up phase of a CPAP humidifier and the cooler bedside environment of a hospital ward. Plumbed into the patient airway tube via the 0.19" male port, it provides real-time airflow data for closed-loop pressure control without requiring external amplification or linearization.

HVAC Differential / Static Pressure Sensing
In HVAC duct and filter monitoring applications, the MPX5010GP delivers the static pressure measurements (0 to 10 kPa) needed to detect clogged air filters, blocked coils, or fan performance issues. Its vented gauge port references ambient pressure, allowing installation at any point in the ductwork without altitude recalibration. The 4.5 V analog swing provides enough resolution to detect sub-100 Pa pressure drops when paired with a 12-bit or higher ADC, while the on-chip signal conditioning eliminates external op-amps that would otherwise need thermal management. Building automation controllers can read the sensor via a single ADC channel and convert the value to Pascal units with minimal firmware overhead.

Industrial Vacuum and Process Control
The MPX5010GP is well matched to low-vacuum industrial processes such as packaging seal integrity testing, pick-and-place vacuum verification, and pneumatic gripper feedback, where pressures of 0 to 10 kPa cover the typical operating envelope. Its ±1.5% factory calibration supports direct use in process-control loops without inline trim, and its 5 V single-supply operation simplifies integration with PLC analog input modules. The 6-SIP Unibody package withstands typical industrial vibration when properly retained, and the on-chip ASIC eliminates long analog signal paths that would otherwise pick up motor and relay noise.

Consumer Appliance Load / Vacuum Sensing
In vacuum cleaner suction control and washing-machine water-level switches, the MPX5010GP provides a low-cost analog pressure reading that maps to load or blockage conditions. Its ratiometric output is tolerant of the long, unregulated wiring typically found in appliances, and the 0.2 V zero offset can be trimmed out in software using the existing motor controller's ADC. The on-chip temperature compensation keeps readings accurate across the cold-start to full-load thermal envelope of an appliance cycle, and the standard 0.19" male port mates with inexpensive flexible tubing used throughout the appliance industry.

Drone and Portable Altitude Estimation
Drones and handheld outdoor instruments can use the MPX5010GP for low-cost altitude estimation when paired with a temperature reference, leveraging the linear relationship between atmospheric pressure and elevation. The 0 to 10 kPa range corresponds to about 0 to 8 kPa deviations from sea-level reference (offset handling required in firmware), and the ratiometric output preserves accuracy as the LiPo battery drains from 4.2 V to 3.7 V with appropriate reference scaling. The compact 6-SIP package suits dense flight-controller boards, and the on-chip amplifier reduces external BOM count - a critical factor for weight-sensitive UAV designs.

Blood Pressure Monitor Air-Pressure Sensing
The MPX5010GP serves as the air-pressure transducer in electronic sphygmomanometers, where it reads cuff pressure from 0 to roughly 30 kPa during inflation and 0 to about 20 kPa during measurement, well within the 10 kPa range when paired with a controlled cuff deflation rate. Its analog output drives an ADC-based oscillometric algorithm that infers systolic and diastolic pressures from the cuff pulsation envelope. The on-chip temperature compensation and ±1.5% factory calibration ensure readings remain consistent across ambient conditions encountered in pharmacies, clinics, and home use.

Ghi chú thiết kế
Place a 100 nF ceramic decoupling capacitor within 5 mm of the MPX5010GP supply pin to suppress switching noise from nearby digital logic. Use wide, short traces for Vs and GND, and consider a small RC filter (for example, 100 ohm plus 100 nF) on the output line to reduce ADC sample-to-sample variation caused by MCU reference noise.
Mount the sensor with the pressure port facing downward or sideways as shown in the datasheet; mounting the port face-up can trap moisture or debris and introduce zero-shift errors. Avoid running pneumatic tubing across sharp PCB edges and use flexible silicone tubing rated for negative pressure if used in vacuum or pump-side applications.
Because the output is ratiometric to Vs, use the same 5 V rail - or a precisely divided reference of it - as the ADC reference voltage. Using an independent ADC reference and varying Vs will produce apparent pressure shifts; this is a common source of "drift" complaints that are actually a design-level calibration issue rather than sensor inaccuracy.
Do not exceed the maximum overload pressure specification (see datasheet) - applying overpressure can permanently alter the zero offset and degrade linearity. Avoid connecting the vent port to a sealed volume; the sensor requires atmospheric reference to function as a gauge device. For liquid media, install an inline isolation membrane; the silicon die is not rated for direct liquid contact.
