Sensor Data Exchange (SDX)


SDX is part of Smart Nation Sensor Platform (SNSP), a Strategic National Project. It is a centralised platform that distributes sensor data across Whole-of-Government (WOG). It provides seamless and secure data sharing and management, and encompasses public, private, and industrial internet-of-things.

SDX enables government agencies to:

  • Publish and subscribe (near) real-time sensor data using a self-service portal both government intranet and government commercial cloud.

  • Share unclassified (potentially up to restricted) sensor data with government sector organisations

An illustration of the components of SDX and its ability to distribute sensor data across networks:

How SDX works


  • Sensor marketplace: Publish and subscribe to data across government agencies for comprehensive insights

  • Support multiple protocols: MQTT, AMQP, REST, and so on

  • Data transfer in real-time: Enable sensor data to be distributed across government agencies in real-time for timely responses and predictive analytics

  • Data sharing across network zones: Secure cross-zone data exchange across internet, intranet, and private networks

  • Self-service portal: Along with workflow engine

  • Data sharing and ingestion on internet

Key benefits

  • Exchange as a service

    • Subscription based

    • No heavy investment in infrastructure

    • Manage core infrastructure and MPLS circuit to the perimeter of agency network

  • Robust architecture for smart systems

    • Versatile in supporting event-driven distributed data and unpredictable workload

    • Ability to abstract and distribute data

    • Manage technical complexity of cross zone integration and protocol translation

  • Spur innovation

    • Ease to equip data scientist with data that is not readily available in their agency

    • Create a culture of sharing for innovation to flourish
