ABSTRACT
This chapter discusses several design considerations, such as sensor node, network, and transmission frequency for the development of low-power Internet of Things (IoT) wireless sensor networks (WSNs). WSNs have been deployed in different applications to collect useful information. The chapter presents IoT wireless technologies, existing WSN platforms, and IoT hardware platforms with low-power management and energy harvesting for power supply. Many IoT wireless technologies use the industrial, scientific and medical (ISM) license-free spread spectrum to transmit data. The ISM band is internationally reserved for the use of industrial, scientific and medical equipment other than telecommunications. IoT hardware platforms provide the ability to develop, manage, and deploy IoT applications at nodes. IoT wireless sensor network platforms are constructed by integrating sensors, IoT hardware platforms and long-range wireless communication modules. MEMSIC’s wireless sensor nodes are used to form WSN systems for environmental monitoring applications.
