We have Developed an IoT-based real-time solar power monitoring system in this paper. It seeks an opensource IoT solution that can collect real-time data and continuously monitor the power output and environmental conditions of a photovoltaic panel.The Objective of this work is to continuously monitor the status of various parameters associated with solar systems through sensors without visiting manually, saving time and ensures efficient power output from PV panels while monitoring for faulty solar panels, weather conditionsand other such issues that affect solar effectiveness.Manually, the user must use a multimeter to determine what value of measurement of the system is appropriate for appliance consumers, which is difficult for the larger System. But the Solar Energy Monitoring system is designed to make it easier for users to use the solar system.This system is comprised of a microcontroller (Node MCU), a PV panel, sensors (INA219 Current Module, Digital Temperature Sensor, LDR), a Battery Charger Module, and a battery. The data from the PV panels and other appliances are sent to the cloud (Thingspeak) via the internet using IoT technology and a Wi-Fi module (NodeMCU). It also allows users in remote areas to monitor the parameters of the solar power plant using connected devices. The user can view the current, previous, and average parameters of the solar PV system, such as voltage, current, temperature, and light intensity using a Graphical User Interface. This will facilitate fault detection and maintenance of the solar power plant easier and saves time.

Abstract Environmental and safety sensing is becoming of high importance in the oil and gas upstream industry. However, present solutions to feed theses sensors are expensive and dangerous and there is so far no technology able to generate electrical energy in the operational conditions of oil and gas extraction wells. In this paper it is presented, for the first time in a relevant environment, a pioneering energy harvesting technology based on nanomaterials that takes advantage of fluid movement in oil extraction wells. A device was tested to power monitoring systems with locally harvested energy in harsh conditions environment (pressures up to 50 bar and temperatures of 50ºC). Even though this technology is in an early development stage this work opens a wide range of possible applications in deep underwater environments and in Oil and Gas extraction wells where continuous flow conditions are present.

For factory automation, devices and machine make a lot of space has become crowded and full of workers makes the operation of the pipeline space is limited, the problem of accidents become more frequent as the frequency will gradually floating surface have to seriously. The combination of embedded systems based on ZigBee technology to enhance the quality of research objectives of industrial safety, in addition to the general control inherent in using the system outside the ZigBee wireless technology to a remote control. Industrial application platform measurements have the thickness of the degree of screening, vibration sensor, weight classification, current sensing, energy monitoring, load switching, temperature monitoring, and carbon dioxide concentration. From the existing literature found in this study combined with embedded ZigBee for industrial real-time measurement system is an innovative technology. In this study, in addition to the discussion platform, the data for statistical measurement and analysis are also discussed in detail, through wired and wireless synchronization of the system measurement and monitoring, will be able to reach a real-time and can improve the safety of plant safety monitoring.
