Smart Electrical DB POC

Smart DB POC

Singapore is engineering its transformation into a Smart Nation – byte by byte, system by system. These Strategic National Projects are the foundation for turning this vision into reality.

​Punggol Smart Town

Bringing together residents, businesses and students, Punggol is slated to become a thriving, tech-enabled, sustainable town showcasing our Smart Nation ambitions.

​Singapore’s highly-anticipated “smart district” that brings together industry and academia with the wider community to foster a vibrant, strong digital community! A thriving community of people will also be calling this neighbourhood home. With shared public spaces and hi-tech community facilities, PDD will be connected to the Punggol waterfront by green links for the community’s recreational needs.

​Such Smart HDB is going to be equipped with the below features
