  Smart living is a trending lifestyle that envisions lower energy consumption,
sound public services, and better quality of life for human being. The Internet
of Things (IoT) is a compelling platform connecting various sensors around us
to the Internet, providing great opportunities for the realization of smart
living. Spintronic sensors with superb measuring ability and multiple unique
advantages can be an important piece of cornerstone for IoT. In this review, we
discuss successful applications of spintronic sensors in electrical current
sensing, transmission and distribution lines monitoring, vehicle detection, and
biodetection. Traditional monitoring systems with limited sensors and wired
communication can merely collect fragmented data in the application domains. In
this paper, the wireless spintronic sensor networks (WSSNs) will be proposed
and illustrated to provide pervasive monitoring systems, which facilitate the
intelligent surveillance and management over building, power grid, transport,
and healthcare. The database of collected information will be of great use to
the policy making in public services and city planning. This work provides
insights for realizing smart living through the integration of IoT with
spintronic sensor technology.
