Pressure
Air and Liquid Pressure Sensor
- Overview
- Commands
- Samples
- On-Module Code
An air and liquid pressure sensor with a small barbed pipe input — connect a tube and read the pressure with simple text commands over any supported interface. Conditioning and scaling are handled on the module so your host code gets a clean value.
Common uses: air bladder monitoring, hydraulic pressure feedback, water-column / tank-level estimation, breath-strength meters, and weather-station altimetry.

Modules ship without cables to reduce waste. Some specialty boards include a USB cable; for the rest, see Cables to add cables to your order.
Commands this module accepts. See Samples for runnable code in popular host languages.
| Function | Description |
|---|---|
kPa() | Returns value in kPa |
Psi() | return value in PSI |
DVer() | This driver version. |
Peek under the hood
The script below is this module's driver — it teaches the hardware how to respond to the commands listed above. It ships pre-loaded from the factory; most users never need to open it.

This sample runs in MicroBlocks on a any host board that's connected/tethered to this module, or a chain of modules. This module keeps its official DUELink firmware and module driver and responds to commands from the connected MicroBlocks-running host. New here? See the MicroBlocks page.
There are two ways to use it:
Open the full sample — the complete project (the module's library plus a ready-to-run example) opens directly on the MicroBlocks website.
Add just the libraries to your own project — copy the link, then in your MicroBlocks project click Add Library → Cloud and paste it. This loads this module's libraries into your project without replacing your current work.
Copy Library LinkCode that runs directly on this module's MCU. See how On-Module Code allows modules to run standalone.
- Script
- Arduino IDE
This example runs using the default DUELink Internal Engine using its Scripting Language, and it expects the module's driver to be loaded first, see the Commands Tab.
