Abstract Technological advances in the Internet of Things (IoT) have paved the way for wireless technologies to be used in new areas. Agricultural monitoring is an example where IoT can help to increase productivity, efficiency, and output yield. However, powering these devices is a concern as batteries are often required due to devices being located where electricity is not readily available. In this paper, an experimental comparison is performed between IoT devices with energy harvesting capabilities that use three wireless technologies: IEEE 802.11 g (WiFi 2.4 GHz), IEEE 802.15.4 (Zigbee), and Long Range Wireless Area Network (LoRaWAN), for agricultural monitoring. Four experiments were conducted to examine the performance of each technology under different environmental conditions. According to the results, LoRaWAN is the optimal wireless technology to be used in an agricultural monitoring system, when the power consumption and the network lifetime are a priority.

使用具有能量收集功能的物联网设备进行智能农业监测的无线技术

摘要 物联网 (IoT) 的技术进步为无线技术在新领域的应用铺平了道路。农业监测是物联网可以帮助提高生产力、效率和产量的一个例子。然而，为这些设备供电是一个问题，因为由于设备位于不易获得电力的地方，因此通常需要电池。在本文中，对使用三种无线技术的具有能量收集功能的物联网设备进行了实验比较：IEEE 802.11 g (WiFi 2.4 GHz)、IEEE 802.15.4 (Zigbee) 和远程无线局域网 (LoRaWAN)，用于农业监测。进行了四次实验以检查每种技术在不同环境条件下的性能。根据结果​​，
