Digital Remote Electronic Starterproject is developed for the users to control an electronic starter in wireless manner. It consists of five modules. RF receiver, Phase detector, Load monitor, Microcontroller unit and Display unit.

The user can simply operate the starter using a remote. When the user operates the remote, a RF signal is transmitted and it is received by the RF receiver connected with the starter. The RF receiver sends signal to the microcontroller and the microcontroller energize the relays through driver section to operate the motor.

The relays will be energized only if all the phase are available. If any one phase is cut, the microcontroller switches off the motor.

A current transformer is connected with the motor line which monitors the load of the motor. If there is over load, the microcontroller switches off the motor and the status will be displayed in a LCD display.

Since this uses RF signal, there is no need to touch the starter switch which avoids unnecessary shocking.

The microcontroller used is PIC 16F73 and the microcontroller program is written in assembly language
