Smart Home IoT System by Using RF Energy Harvesting

Abstract

IoT system becomes a hot topic nowadays for smart home. IoT helps devices to communicate together without human intervention inside home, so it is offering many challenges. A new smart home IoT platform powered using electromagnetic energy harvesting is proposed in this paper. It contains a high gain transmitted antenna array and efficient circularly polarized array rectenna system to harvest enough power from any direction to increase lifetime of the batteries used in the IoT system. Optimized energy consumption, the software with adopting the Zigbee protocol of the sensor node, and a low-power microcontroller are used to operate in lower power modes. The proposed system has an 84.6-day lifetime which is approximately 10 times the lifetime for a similar system. On the other hand, the proposed power management circuit is operated at 0.3 V DC to boost the voltage to ~3.7 V from radio frequency energy harvesting and manage battery level to increase the battery lifetime. A predictive indoor environment monitoring system is designed based on a novel hybrid system to provide a nonstatic plan, approve energy consumption, and avoid failure of sensor nodes in a smart home.

Recent Progress in Application‐Oriented Self‐Powered Microelectronics

“…Compared to clean energy such as solar and wind power, magnetic energy has received less attention. [544] Maharjan et al [545] designed a magnetic field energy harvester that harvests timevarying magnetic fields around indoor wires (Figure 14c). The energy harvested by the magnetic field energy harvester is supplied to the wireless sensor network through an energy management circuit, and this process has been successfully demonstrated through experiments.…”

A Comprehensive Survey of Security Issues of Smart Home System: “Spear” and “Shields,” Theory and Practice

“…Devices in SHSs are vulnerable to energy theft, particularly passive devices. There are many solutions for energy attacks, such as optimizing energy consumption, confusing energy generation, energy regeneration, electromagnetic energy collection [72] and magnetic field energy collection based on indoor power lines [73]. Addressed to energy savings, Zungeru et al [74] proposed a secure energy exchange system based on wireless communication and energy self-collection.…”

“…Penggunaan internet dan perkembangan Internet of Things (IoT) yang begitu pesat mendorong semakin banyaknya peminat smart home saat ini [2]. Disamping itu, layanan yang disediakan oleh sistem smart home menjadi fitur utama, layanan yang tersedia tentunya tidak terlepas dari data yang dikumpulkan dari sensor dan ketersediaan fungsi untuk pengontrolan [3]. Dalam smart home monitoring dilakukan berdasarkan data sensor yang tersedia yang diolah menjadi informasi yang diperlukan oleh pengghuni rumah.…”
