GSM CONTROLLED DOL STARTER FOR PUMP MOTOR

GSM CONTROLLED DOL STARTER FOR PUMP MOTOR




A GSM controlled DOL starter for a pump motor is a system that uses the Global System for Mobile (GSM) network to remotely control a Direct-On-Line (DOL) starter for a pump motor. The DOL starter is an electromechanical device used to start and stop motors by connecting them directly to the power source. The system uses a microcontroller, a GSM module, and a relay to send commands to the DOL starter over the GSM network.

The following are the components needed to build a GSM controlled DOL starter for a pump motor:

  • Microcontroller (e.g. Arduino Uno)

  • GSM module (e.g. SIM800L)

  • Relay module

  • DOL starter

  • Pump motor

  • Power supply (e.g. 12V DC)

The system works by sending commands to the microcontroller through SMS messages. The microcontroller then sends a signal to the GSM module to receive the SMS message. The GSM module reads the message and sends the appropriate signal to the relay module to switch the DOL starter on or off, which in turn controls the pump motor.

Here are the basic steps to build a GSM controlled DOL starter for a pump motor:

  1. Connect the microcontroller, GSM module, and relay module to the power supply.

  2. Connect the microcontroller and GSM module through serial communication.

  3. Install the DOL starter and connect it to the relay module.

  4. Connect the pump motor to the DOL starter.

  5. Write a program for the microcontroller to receive SMS messages and control the DOL starter using the relay module.

  6. Test the system by sending SMS messages to the GSM module to control the pump motor.

The advantages of a GSM controlled DOL starter for a pump motor include remote control of the pump motor, reduced energy consumption, and increased safety. The system is useful in situations where the pump motor is located in a remote location or in hazardous environments where manual control is not feasible.

However, it is important to note that proper safety measures and precautions should be taken when working with electricity and motor control systems. It is recommended to consult with a professional electrician or engineer before attempting to build or install a GSM controlled DOL starter for a pump motor.
