A study on the monitoring system of a photovoltaic (PV) power plant using low-cost Internet of Things (IoT) technology for monitoring electrical output (voltage and current) and environmental parameters (solar irradiance and cell temperature) to measure the performance of PV power plant has been realized. The prototype design of the monitoring system developed is the integration of several smart sensors, microcontrollers and algorithms that are able to read, send and process data in real-time. The working principle of IoT in this monitoring system is to connect sensors and devices from special systems on a public network through wired or wireless nodes. In general, IoT-based wireless systems are preferred to avoid the risks associated with wired systems. By still paying attention to the needs in the near future, where every device will be smart, automatic and connected via the internet.
