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.
