Pressure Sensors Philippines: Barometric, Absolute, Differential & Transducers | Circuitrocks
Pressure Sensors at Circuitrocks — Barometric, Absolute, Differential & Industrial
Measure altitude, airflow, fluid level, and line pressure with pressure sensors for Arduino, ESP32, and Raspberry Pi. Choose from compact barometric modules (I²C/SPI), absolute/gauge sensors for liquids and gases, differential parts for airflow, and 0–5V / 4–20 mA transducers for industrial ranges.
Barometric (BMP/BME/DPS) • Absolute/Gauge • Differential • 0–5V & 4–20mA
Why these sensors
-
Wide pressure ranges from Pa to MPa
-
Easy interfaces: I²C/SPI/analog, libraries available
-
Ready for projects: tubing barbs, headers, rugged housings
Typical projects
- Altimeters & weather stations (barometric)
- Water depth/level & pump monitoring (gauge/absolute)
- Airflow & filter health (differential)
Featured categories
Tip: For liquid measurements, confirm wetted-materials compatibility and use an IP-rated enclosure. For 4–20 mA outputs, add a precision shunt/ADC to read current on microcontrollers.
FAQ
Which interface should I pick (I²C/SPI/analog/4–20 mA)?
I²C/SPI offer digital accuracy and libraries; analog is simple and fast; 4–20 mA is robust for long cables and industry—use a shunt/ADC to read it.
Gauge vs absolute vs differential?
Gauge measures relative to ambient; absolute to vacuum (good for sealed systems); differential measures between two ports (airflow/filters).
Can I use these with water?
Use sensors rated for liquids or external transducers. Keep electronics dry, add strain relief on tubing, and check chemical compatibility.
Do you ship nationwide?
Yes—fast shipping anywhere in the Philippines. Same-day processing on in-stock orders before cutoff.
