Design and Development of Overload Warning System

The project involves developing a new automated system to monitor the operating conditions and provide a warning when the machine goes to overload conditions.

Components required

  • Arduino Uno

  • ACS712 current sensor

  • Buzzer

  • Jumper wires

Step1: Connections

Circuit diagram

Make the connections as follows:

  • ACS712 VCC to 5V

  • ACS712 GND to GND

  • ACS712 VOUT to A0 of Arduino

  • Buzzer Positive to Pin 8 of Arduino

  • Buzzer GND to GND

Step2: Arduino Code

Download the Arduino code from the button below and paste it in a new sketch.

Upload the sketch to the Arduino Uno.

Step3: Implementation

After uploading the code to the Arduino Uno, connect the ACS712 current sensor in series with your load side. Make sure that either the positive line or the neutral line is connected.

Be careful not to connect both the positive and negative lines in the sensor simultaneously. This results in a short circuit and is very dangerous.
