ABSTRACT: At present, industries are rapidly shifting towards automation. Today’s industrial automations mostly based on programmable controllers and robots. In order to do the tedious work and to serve the mankind, automation is developed in industries. DC motor plays an important role in various industries hence we selected it. This project present a system to provide protection, control and monitoring the condition of DC motor. Here Arduino Uno and various sensors like current, voltage, speed and temperature sensors are used. Real time values of various parameters like current, voltage, temperature and speed can be monitored in ThingSpeak mobile app. By continuous monitoring, the motor can be protected against fault like short circuits, overloading, overheating etc. hence machine performance is improved.

Keywords: IoT, Arduino Uno, Node MCU, DC motor, LCD, Fault, etc.

1. INTRODUCTION

Nowadaysthereisadvancementintechnologies,inordertoreducethemanpowerinindustries,theindustriesareshifted towardsautomation.DCmotorsareusedinvariousindustriesbecauseoftheirsmallsizeandhighenergyoutput.Themanual controlofmotorindifferentareasofanindustryfortheswitchONorOFFistimeconsumingandinconvenienthereaneffortis madetocontrolautomatically.Protectionormaintenanceisalsoveryimportantaspectforthesmoothoperationofmotorinan industry.ThemonitoringofseveralParametersofmotorlikevoltage,current,temperatureandspeedetc.byhumanisvery time consuming process. These problems are studied and developed a remote project as solution called IOT BASED ELECTRICALMOTORCONTROLANDMONITORING.Inthispaper,acosteffectiveprotectionandcontrolsystemhasbeen developedforDCmotorswhichcanbeusedinpractice.
