“…By installing sensors in objects such as power grids, railways, tunnels, highways, bridges, water supply systems, and oil and gas pipelines, and integrating with the existing Internet, the IoT realizes interconnection between objects. It can be seen in many fields such as intelligent transportation, government work, smart home, environmental monitoring, street lighting management, elderly care, and intelligence collection [36][37][38][39]. Narrowband Internet of Things (NB-IoT), as an important branch of the IoT, has a series of characteristics such as flexible deployment, narrow bandwidth, fast transmission speed, and low energy consumption.…”

With unique electromagnetic properties, metamaterials (MTMs) provide more freedom for antenna design, particularly with the combination of active-device-enabling effective tuning. By integrating the active device and the periodical cells of MTMs, the electromagnetic characteristics of individual cells can be manipulated independently, thereby realizing multiple tunable states for MTM antennas consisting of several periodical cells. In this paper, we employ active devices such as PIN diodes to each periodical cell to tune each cell independently, thereby realizing 36 tunable zeroth-order resonances (ZORs) for the metamaterial antenna with three cells in a frequency range of 4.48–5.34 GHz. Moreover, each ZOR has a bandwidth as narrow as 0.09 GHz, indicating that the tunable ZOR antenna can be potentially applied to 5G Narrowband Internet of Things (NB-IoT).

“…The plant may die in extreme air temperature and humidity conditions [22]. Several works have considered other additional parameters such as gas pressure, hydrogen (H 2 ), liquid petroleum gas (LPG), methane (CH 4 ), carbon monoxide (CO), alcohol, smoke [17], carbon dioxide (CO 2 ) [18,22], light [21,22]. The high concentration of the gases in the air may affect the photosynthesis of the plants [18,22].…”

“…In soil monitoring, the most common parameters are soil moisture [14][15][16][18][19][20]22,[24][25][26], temperature [16,18,20,22,23], pH [20,24,26], nitrogen, phosphorus, and potassium/kalium (NPK) [23][24][25][26][27][28], and electrical conductivity (EC) [26]. The soil moisture represents the water content in the soil.…”

Plant leaf temperature and its environmental parameters provide valuable information on plant growth. This paper presents the development of a plant monitoring system using an IoT-based SCADA (Supervisory Control and Data Acquisition). The developed SCADA system monitors the leaf temperature and the air parameters of temperature and humidity, as well as the soil parameters of temperature, moisture, pH, electrical conductivity, nitrogen, phosphorous, and potassium. A novel method is proposed for measuring the leaf temperature using a low-cost 8 × 8 array thermal camera. The sensor systems in the field are developed to wirelessly communicate with the Hawell IoT Cloud HMI via a Modbus TCP protocol. To visualize the thermal image on the HMI dashboard, a novel approach is proposed wherein the data are transferred using the Modbus TCP protocol. The HMI is connected to a cloud server and can be accessed by the users using the web browser or mobile application on a smartphone. The experimental results show that the proposed hardware, software, and communication protocol are reliable for real-time and continuous plant monitoring. Further, the evaluation of sensor data shows that the data from the thermal camera and air parameters sensor can be independently interpreted. However, the data from the soil sensor should be interpreted in consideration of the other parameters.
