Wireless internet of things solutions for efficient photovoltaic system monitoring via WiFi networks

Abstract

<div align="center"><span>The imperative for sustainable energy production has necessitated the significant expansion of renewable energy sources, particularly photovoltaic (PV) systems. The utilization of real-time monitoring and data analysis is imperative to enhance the efficiency and performance of photovoltaic systems. This abstract presents developing and deploying a wireless monitoring system for a photovoltaic system. The system utilizes a Raspberry Pi device connected to a WiFi network and an SD card for data storage to enable remote monitoring and management of PV systems. The proposed monitoring system comprises a Raspberry Pi equipped with sensors to measure various parameters such as voltage, current, temperature, and the ambient conditions of the solar panels; the monitoring system can be remotely accessible through the wireless capabilities of the Raspberry Pi, which are activated by establishing a connection to an existing WiFi network. The proposed configuration facilitates the placement of the monitoring station in any desired location, hence eliminating the requirement for intricate wiring connections. These real-time data enable solar system managers to quickly identify anomalies, anticipate breakdowns, and optimise energy production. The paper presents a wireless monitoring system with a cost-effective and scalable solution for monitoring photovoltaic systems.</span></div>

An internet of things-based pump and aerator control system

“…The JSN-SR04T sensor is preferred over other ultrasonic sensors because it is a waterproof type of sensor [7]. The MLX90614 sensor is selected over the DHT 11 or DHT 22 sensor because the sensor is contactless-type, making it easier to install [8], [9]. The output of the JSN-SR04T sensor is used as a reference to control the water pump automatically, and the output of the sensor MLX90614 is used to monitor changes in the temperature of the aerator motor to prevent overheating.…”
