The objective of the project is to control the starter from the application and to provide a start motor The starter is turned on/off from the application itself through a Wi-Fi module The webpage is created through which the starter on/off status can be identified and the motor can be turned on/off. Arduino software is used which receives the Wi-Fi module signal from the webpage. The signal from the Arduino in turn controls the starter action through the relay driver circuit. Additionally, the voltage sensor are given as feedback to the Node MCU to protect the motor from overvoltage and overcurrent. Thus the starter can be controlled from the application through the internet.

Introduction

In the day-to-day, life motors play a serious role in the domestic and industrial sectors. regardless of the sort of providing the motors square measure started mistreatment starters. In industrial sectors, manual operation for ON/OFF of the motor might not be reliable. In several instances, the operators in the room might not be on the market to regulate the motor. Recently the technological growth has paid means for numerous automatic starters and controllers. This project is close to management the starter through the web. however high rating motors need a safe operation. the most objective of this project is to regulate the motor and to produce correct protection for the motor. thus during this project, it's projected to model a tool that is dynamic, low-cost, and wireless within the field of motor dominant. Safety of a motor additionally is additionally} a serious concern as a result of non-functional of a motor will cause a large loss in production also increase maintenance value of the motor itself. That's why safety operations are enclosed during this project. One will observe the motor's operation from a distant place and manage it. The motor starter is controlled from the far off through the Wi-Fi module technique mistreatment Arduino software package. The webpage is formed to access On and Off management of the motor through the Wi-Fi module.

Working

Wi-Fi Based Motor Starter Control

The main objective of this project is to control the starter. The control is done by wireless signal transmission.

Motor Control

The starter can be turned on or off by using the button which is created on a webpage. The signal is transferred to the receiving side through a Wi-Fi module which is connected to Node MCU. The starter is turned on or off based on the signal.

On/Off State Detection

The signal received from the webpage enables the Node MCU which in turn operates the relay through the driver circuit. The relay thus controls the on/off state of the starter depending upon the signal received.

Main Components List

1. DOL Starter
2. Relay
3. Power Supply (5)V
4. Node MCU Esp 8266

DOL Starter

Different beginning ways area unit used for beginning induction motors as a result of Induction Motor attracts a lot of beginning current throughout beginning. to stop injury to windings because of high beginning current flow, we tend to use differing kinds of starters. only style of motor starter for induction motor is that Direct On Line starter. The Direct On Line Motor Starter (DOL) consists of an MCCB logic gate Breaker, Contactor associated with an overload relay for defense. Magnetic force contactor which may be opened by thermal overload relay underneath fault conditions. Typically, contractor is going to be controlled by separate begin and stop buttons, associated an auxiliary contact on contactor is employed, across beginning button, as a hold to bear. I.e. contactor is electrically bolted closed whereas motor is working.

Relay

A relay is an associate electrically operated switch. several relays use an associate magnet to control a switch mechanism automatically, however alternative in operation principles also are used. Relays area unit used wherever it's necessary management to regulate to manage} a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or wherever many circuits should be controlled by one signal.

the primary relays were utilized in long-distance telegraph circuits, continuance the signal returning in from one circuit and re-transmitting it to a different. Relays were used extensively in phone exchanges and early computers to perform logical operations. A type of relay that may handle the high power needed to directly drive an electrical motor is termed a contactor. Solid-state relays management power circuits with no moving elements, instead of employing a semiconductor to perform the switch. Relays with the label in operation characteristics and typically multiple in operation coils area unit accustomed shield electrical circuits from overload or faults; in fashionable wattage systems these functions area unit performed by digital instruments still known as "protective relays".

Power offer (5)V

The circuit wants voltages, +5V, to work. These voltages are equipped by this specially designed power offer. The power offer, the unsung hero of each electronic circuit, plays a vital role in the sleek running of the connected circuit. the most objective of this 'power supply' is, because the name itself implies, to deliver the specified quantity of stabilized and pure power to the circuit. each typical power offer contains the subsequent sections.
