SIRMA™ (Smart Interoperable Real-time Maritime Assembly)

SIRMA™ consists of a low-power modular printed circuit board embedded between the two ends of a cable assembly. This assembly allows several functionalities such as data processing, data logging, and voltage regulation between a sensor and a platform such as a glider, AUV, or buoy. SIRMA™ turns any cable assembly from a passive device into a smart processing unit.

Basic Onboard Modules:

  • 32-bit Microcontroller
  • Step-up / Step-down Voltage Regulators
  • Flash Memory Unit
  • 16-bit Analog to Digital Converter (ADC)

Input / Output Communication Protocols:

  • RS-232
  • RS-485/422
  • Ethernet
  • Analog voltage
  • 4 – 20 mA current loop
  • CAN bus

Optional Modules:

  • Real-Time Clock (RTC)
  • Wi-Fi
  • microSD bank – up to 4TB storage
  • More custom modules upon request

Software and Hardware is open-source and available on GitHub

SIRMA™ was developed through the SMART Cable Project — a part of the Research & Innovation Foundation Framework Programme RESTART 2016-2020 for Research, Technological Development and Innovation. SMART Cable is co-funded by the Republic of Cyprus and the European Regional Development Fund (Grant number ENTERPRISES/0916/0066).
