Small green circuit board with silver sensor and 2.5 mm tube fitting

YINGHUA

YINGHUA digital pressure sensor module 0-40 kPa 2.5 mm tube 3.3 V/5 V

SKU CH-51BJ-FPKSX

Measures pressure from 0 to 40 kPa with a 2.5 mm tube and 3.3 V or 5 V supply

  • Measures up to 40 kPa for precise low-pressure monitoring
  • Works with both 3.3 V and 5 V logic without extra level shifting
  • 5 mm tube interface fits standard pneumatic tubing directly
  • Digital output simplifies microcontroller integration with no analogue conditioning needed

Digital pressure sensor module 0-40 kPa

This digital pressure sensor module measures from 0 to 40 kPa and operates on either 3.3 V or 5 V supply rails. It is intended for engineers and hobbyists who need a compact, dual-voltage pressure input for data-logging or control projects. The 2.5 mm tube interface accepts standard flexible tubing for direct connection to the media being monitored. No additional signal conditioning is required for typical microcontroller ADC inputs.

Replaces analogue sensor circuits

Upgrade when your design needs a wider supply-voltage tolerance or a digital output that removes the need for an external ADC stage. The jump is worth it if you are moving from a 5 V-only sensor and must run the same board on a 3.3 V MCU, or when the 0-40 kPa range matches a new application requirement. Builders who need a higher pressure range or a different tube diameter should select an alternative module.

Highlights

  • Measures up to 40 kPa for precise low-pressure monitoring
  • Works with both 3.3 V and 5 V logic without extra level shifting
  • 5 mm tube interface fits standard pneumatic tubing directly
  • Digital output simplifies microcontroller integration with no analogue conditioning needed

Questions about this item

What size tube does the 2.5 mm interface on this sensor module accept?

The module has a 2.5 mm tube interface for direct connection to tubing of that diameter.

Which supply voltages does the 3.3 V/5 V dual-voltage module support for installation?

It operates from either a 3.3 V or a 5 V supply, so you can power it from either rail without a level shifter.
