CrowPanel ESP32-P4 v1.2 Application Demo

OpenPLC HMI for Industrial Equipment

An operator panel example for monitoring and controlling industrial equipment.

Demo

Compressed-Air Station HMI in Action

The demo shows a complete compressed-air station in operation. The HMI displays equipment status, process parameters, controls, alarms, and live trends.

All process data is generated by the built-in simulator. No PLC or external equipment is required to run the demo.

The user can:
  • ✓Monitor the status of the entire station
  • ✓View detailed data for individual compressors and other equipment
  • ✓Switch between automatic and manual operating modes
  • ✓Start and stop equipment
  • ✓Inject a test sensor fault
  • ✓Observe how an alarm appears
  • ✓Follow changing process values on live trend charts
Live station behavior. The process keeps changing after startup: air demand varies automatically, compressors are dispatched as demand rises and stopped as it falls, while pressure, power, temperature, motor current, runtime, equipment states, trends, and alarms update continuously. Switch a compressor to manual mode for direct start/stop control, or inject a sensor fault to see how the abnormal condition appears across the HMI.
Free demo firmware

Run the Demo on CrowPanel ESP32-P4 v1.2

Download the firmware, flash your CrowPanel, and launch the demo.

After startup, a short presentation is shown first. Then the HMI opens with a live simulated compressed-air station, including equipment states, controls, process values, alarms, and trends.

Customization

From Demo to Your HMI

This demo runs entirely on CrowPanel using a built-in compressed-air station simulator. It allows the HMI concept, operator workflows, controls, alarms, and trends to be evaluated without connecting a PLC or external industrial equipment.

The same approach can be adapted to your equipment and connected to real controllers and data sources for a production project.

Customization can include:
  • ✓Your equipment and system structure
  • ✓Your process data, states, and control commands
  • ✓UI and branding
  • ✓Alarms, trends, and operator workflows
  • ✓OPC UA and other required integrations
  • ✓CrowPanel hardware configuration
First step

See the Demo in Action

Buy a CrowPanel, install the free demo firmware, and evaluate the HMI concept on real hardware.

  • Development cost at this stage: 0
  • Physical working demo for technical evaluation or internal presentation
  • No PLC or external equipment required
Next step

Order a Prototype for Your Use Case

Within 2 weeks, a tailored prototype can be prepared around your requirements.
