Monitoring system of photovoltaic panels using 433 MHz radio frequency module

Abstract

In this article, we presented an innovative study that allows direct monitoring of the main parameters of photovoltaic panels. Our study focuses on the skills of radio frequency modules to send the main parameters of photovoltaic cells. In this paper, we used an Esp32 microcontroller in the radio frequency (RF) transmitter block and an Arduino Uno board in the receiver block, in addition, to measure current, we used a current sensor, and to measure voltage, we implemented a voltage divider. After that, we calculated the power and the energy. Note that the various measured and calculated values are stored and used via the ThingSpeak platform. In comparison with similar studies, our achievement presents an` effective and inexpensive solution because its operating principle is based on radio frequency transmission, so it works perfectly even in the absence of the internet. Finally, our study was very well tested without detecting any abnormalities, and the results obtained are a perfect witness to our success.

Implementation of a low-cost intelligent street light system using internet of things

“…This system is equipped with INA219 current/voltage sensors installed in each solar street light, with LDR sensors to detect the beginning of the day and night, with Arduino boards, and with Xbee modules for data transmission between the different street lights using the ZigBee protocol. The system also consists of a Wifi module named ESP8266 for data transmission between the solar street lights and the monitoring application which is hosted in the Thingspeak platform [11], [12].…”

Monitoring of submersible pumps using ESP32 microcontroller and photovoltaic panels

“…Modern irrigation is currently undergoing a major evolution as it has become a decisive factor in water conservation. In this article, we propose a method for designing and building a remote supervision system for smart irrigation to efficiently manage a solar submersible pump, our irrigation system is based on an ESP32 microcontroller and via a sensor Soil moisture, allows essential parameters such as temperature and soil moisture to be measured effectively, this system will feature connectivity allowing the farmer to monitor these quantities in real-time on a dynamic web interface (PC or Smartphone), or receive SMS or Email notifications to efficiently operate this pump and significantly save water this study is based on the use of radiofrequency modules as the main communication element between the different blocks of this design [1].…”
