DESIGN AND CONSTRUCTION OF IOT MONITORING DEVICE FOR 5KVA FULL SINEWAVEINVERTER
Abstract
This project presents the design and implementation of a telemetricvoltagesensor system utilizing the SIM800L GSM module for remote monitoringofelectrical parameters. The system is built around a microcontroller unit thatinterfaces with a voltage sensor to measure input voltages ranging from0–25V. Themeasured values are processed and transmitted wirelessly via SMS using theSIM800Lmodule, enabling users to receive real-time voltage data on their mobile devices. Avoltage regulator (LM2596) ensures stable power supply to both the SIM800Landthe microcontroller, while a 16 MHz crystal oscillator and capacitors provideclockstability for precise operation. The proposed system offers a cost-effectiveandreliable solution for remote electrical monitoring applications such as renewableenergy systems, battery-powered devices, and industrial equipment. Its integrationof GSM technology with simple voltage measurement enhances safety, reducesmanual inspection, and improves efficiency in power systemmanagement.
