Project Overview

To ensure operator safety and improve the reliability of pressure readings during dynamic impact tests, I designed and implemented an Arduino-integrated pressure monitoring system for our Split Hopkinson Pressure Bar (SHPB). The custom system connects Ashcroft G2 pressure transmitters directly to Arduinos, enabling live voltage and pressure data to be streamed to a laptop interface.

The left schematic shows the pneumatic system layout, while the right image captures the actual lab setup, where cables have been shortened for visibility. In operation, the monitoring laptop is placed over 20 feet away to ensure user safety during projectile firing.

Wiring & Hardware Configuration

Connectivity

This section demonstrates how the G2 Ashcroft pressure transmitter was integrated into the Arduino Uno to enable real-time pressure monitoring of the gas chamber. The transmitter was wired with a 3-pin setup: power (V+), ground (GND), and signal (analog out to A0). Once connected, the Arduino was powered with a 12V supply and linked to a laptop via USB, allowing continuous data acquisition and visualization of internal pressure values. This setup provided a reliable, remote sensing system for live diagnostics during SHPB testing.

Live Pressure Monitoring & Remote Vent/Fire Controller

Descriptions

On the left is the live pressure monitor output from the Arduino Uno, displaying real-time pressure values with milisecond response times. I programmed the Arduino code to process the sensor’s analog signals and map them to pressure values in psi. View my code on Github.

The right image shows a physical remote switch used to vent or fire the system. The integrated remote switch enables users to either vent the system if pressure exceeds a threshold or fire when ready, providing safe and controlled SHPB operation.
