IOT Based Control and Protection System of single-phase motor.

Introduction

The IoT-Based Control and Protection System of a Single-Phase Motor is designed to enable remote motor operation and improve electrical safety through real-time monitoring. Using a microcontroller, sensors, and an IoT platform, the system monitors motor operating conditions and provides protection against selected faults, such as overload, overcurrent, and abnormal voltage. It offers a practical approach to smart motor management in domestic, agricultural, and small industrial applications.

Objectives

  • To control a single-phase motor remotely using IoT.

  • To monitor motor voltage and current in real time.

  • To detect overload and abnormal operating conditions.

  • To disconnect the motor automatically during faults.

  • To send fault notifications to the user.

  • To improve motor safety and operational reliability.

Methodology

  • Connect voltage and current sensors to the motor monitoring circuit.

  • Integrate a microcontroller with Wi-Fi connectivity.

  • Connect a suitably rated relay or contactor to control the motor.

  • Develop an IoT dashboard for remote monitoring and operation.

  • Program fault detection and automatic shutdown functions.

  • Configure notifications for abnormal motor conditions.

  • Test remote control, sensor readings, and protection responses under controlled conditions.

Instrument List

  • ESP32 or NodeMCU

  • Single-Phase AC Motor

  • Voltage Sensor

  • Current Sensor

  • Relay Module or Contactor

  • Motor Protection Circuit

  • Wi-Fi Communication Module

  • LCD Display

  • Buzzer

  • IoT Monitoring Platform

  • Regulated Power Supply

  • Fuse or Circuit Breaker

Working Principle

The voltage and current sensors continuously monitor the motor's electrical parameters and send the readings to the microcontroller. The controller displays the data locally and transmits it to an IoT dashboard through Wi-Fi. Users can issue remote start or stop commands, which the controller processes through the motor switching circuit. If the system detects a configured fault, such as excessive current or abnormal voltage, it disconnects the motor and sends an alert to the user.

Advantages

  • Remote motor operation

  • Real-time electrical monitoring

  • Automatic fault protection

  • Fault notifications through IoT

  • Reduced risk of motor damage

  • Convenient motor management

  • Suitable for smart automation

Conclusion

The IoT-Based Control and Protection System of a Single-Phase Motor combines remote operation, electrical monitoring, and automatic fault response. It helps users supervise motor performance and respond quickly to abnormal conditions. Reliable operation depends on sensor calibration, correct protection settings, and appropriately rated switching devices. The IoT system should supplement certified motor-protection equipment, with mains wiring and installation handled by a qualified electrician
