The main aim of this project is to design an IoT based AC motor monitoring system using arduino nano. This system monitor the speed, current, voltage and temperature of AC motor and update this values into the thing speak cloud through esp8266 Wi-Fi module and display this values on LCD while running. In this we can control the motor speed in two levels using regulator. We can monitor the current and voltage readings of motor using sensor. IR SENSOR is uses to measuring the speed (RPS) of motor which is attached near by the motor shaft. LM35 temperature sensor is uses to measure the temperature of the motor. ThingSpeak is an open-source Internet of Things (IoT) application and API to store and retrieve data from things using the HTTP protocol over the Internet or via a Local Area Network. This IoT device monitors the motor readings like voltage, current temperature and speed and updates them into an IoT thigspeak cloud platform. We can increase the monitoring techniques by making use of advanced technology. The project makes a use of arduino nano Microcontroller; it is a main controlling device of the project. To perform the task, Microcontroller is loaded with an intelligent program written in embedded ‘C’ language.  

The main objectives of the project are:

1. Monitoring of speed, temperature, current and voltage of AC MOTOR.
2. Display the motor readings on LCD display.
