The implementation of wireless communication technologies for monitoring and control systems resulted in the first instance of "smart" farming. Precision agriculture (PA) is characterized by the employment of cutting-edge technology and equipment calibrated to the inch to precisely monitor and treat crops. Smart PA is able to assist farmers in increasing crop yields and simultaneously increasing efficiency and reducing stress by utilising wireless sensor networks (WSNs) and the Internet of Things (IoT). In this paper, an Internet of Things–enabled agricultural monitoring system is discussed. Data on the environment will be gathered in the field by solar-powered prototype nodes, and then transmitted to a central station for processing. Utilizing two nodes, it was determined whether or not it is advantageous to add energy harvesting into an electrical device. An experimental testbed demonstrates how the system might work in the future by capturing energy. Using a gadget that can harvest energy can lengthen the amount of time a device is able to run by supplying it with electricity, charging the battery, and increasing the battery's capacity.
