Project Description

Alternative Design Manufacturing & Supply contacted Robust Device to provide electronics design services for the development of their next generation MACS Tower air handler. Robust Device worked closely with Alternative Design to develop their product, having it ready in time to delight customers and surprise their competition at their annual trade show.

The hardware design was composed of three PCBs: a WiFi-enabled main controller board, remote sensor boards, and a battery management board. The design requirements included:

  • touch screen display for status information and user control
  • development of a remote sensor system located in the air streams
  • extremely precise measurement and control of airflow
  • firmware update via USB
  • USB datalogging
  • Wifi connectivity for datalogging and emergency alert notifications
  • cloud hosting and error monitoring
  • development of a battery backup system to allow for uninterrupted service
  • intercommunication and control between all subsystems using a proprietary communications protocol
  • modularity of design to allow for multiple product configurations

Our continuing partnership allows Alternative Design to strategically develop software upgrades to meet the requirements of the changing marketplace.
