[Munir Muhammad]

In this tutorial, we will demonstrate how to build an efficient overload motor protection system using an Arduino and a current sensor. Motor overload can lead to overheating and damage, so it's crucial to implement a reliable protection mechanism. We will explain the working principle of the system and provide a step-by-step guide on connecting the current sensor to the Arduino. Additionally, we will showcase the programming code required to monitor the motor's current and trigger a protective action if an overload is detected. Whether you're a hobbyist or an engineer, this video will equip you with the knowledge to safeguard your motors effectively.

Code:-

#define Relay A1
int analogPin = A0; // Current sensor output


long int sensorValue = 0;  // variable to store the sensor value read


void setup() {
  Serial.begin(9600);           //  setup serial
  pinMode(Relay, OUTPUT);
}

void loop() {

 
    sensorValue = analogRead(analogPin);

    // wait 2 milliseconds before the next loop
    delay(200);


 
  Serial.println("ADC Value: ");
  Serial.println(sensorValue);
// set value on which you want to switch off Motor. normally motor oprate between value 512 to 525.
// I set 530 value on which motor switch off for 5 seconds.
//if(sensorValue > 530)
if(sensorValue > 550)
{
   digitalWrite(Relay, LOW);
   delay(5000);
}
else
{
  digitalWrite(Relay, HIGH);
  }

The provided code demonstrates how to build an efficient overload motor protection system using an Arduino and a current sensor. It monitors the motor's current and triggers a protective action if an overload is detected. Here's a breakdown of the code:

cpp

#define Relay A1 int analogPin = A0; // Current sensor output long int sensorValue = 0; // variable to store the sensor value read void setup() { Serial.begin(9600); // setup serial pinMode(Relay, OUTPUT); } void loop() { sensorValue = analogRead(analogPin); // Read the analog value from the current sensor delay(200); // Wait for 200 milliseconds Serial.println("ADC Value: "); Serial.println(sensorValue); // Print the sensor value to the serial monitor // Set the threshold value at which you want to switch off the motor // In this example, if the sensor value exceeds 550, the motor will switch off for 5 seconds if(sensorValue > 550) { digitalWrite(Relay, LOW); // Switch off the motor delay(5000); // Delay for 5 seconds } else { digitalWrite(Relay, HIGH); // Keep the motor running } }

In the setup() function, the serial communication is initiated with a baud rate of 9600, and the Relay pin is set as an output. In the loop() function, the analog value from the current sensor is read using analogRead(). The sensor value is then printed to the serial monitor for monitoring purposes.

If the sensor value exceeds the defined threshold of 550, the relay pin is set to LOW, turning off the motor. The delay of 5 seconds is applied to keep the motor off for that duration. If the sensor value is below the threshold, the relay pin is set to HIGH, allowing the motor to continue running.

Make sure to properly connect the current sensor to the Arduino, and adjust the threshold value according to your motor's specifications and desired protection leve
