  Internet of Things (IoT) technologies are the foundation of a fully connected
world. Currently, IoT devices (or nodes) primarily use dedicated sensors to
sense and collect data at large scales, and then transmit the data to target
nodes or gateways through wireless communication for further processing and
analytics. In recent years, research efforts have been made to explore the
feasibility of using wireless communication for sensing (while assiduously
improving the transmission performance of wireless signals), in an attempt to
achieve integrated sensing and communication (ISAC) for smart IoT of the
future. In this paper, we leverage the capabilities of LoRa, a long-range IoT
communication technology, to explore the possibility of using LoRa signals for
both sensing and communication. Based on LoRa, we propose ISAC designs in two
typical scenarios of smart IoT, and verify the feasibility and effectiveness of
our designs in soil moisture monitoring and human presence detection.
