Password based jail chamber gate operation by motor

Description

The microcontroller-based door locker is an access control system that allows only authorized persons to access a restricted area. The system is fully controlled by the 8-bit microcontroller. A matrix keypad is interfaced to the microcontroller to enter the password while a motor driver IC is used to switch on the motor. The complete circuit is built with a board power supply. This system consists of the multiple channel access control which comprises the different passwords of each system.

The Password-based jail chamber gate operation by the motor system will open with their individual passwords. If the password at any phase is wrong the there will an alarm for the system. It has multiple door control with a different authenticated password to open.

This Password-based jail chamber gate operation by motor feature can be used to identify the key pressed using a controller. Here the keypad number is decoded through presses. These decoded numbers are fed into the microcontroller. It checks the correctness of the code. If the code is correct then the motor is energized to open the gate and in case the code is not correct or somebody tries to unlock it by using some other way then it will give the alarm.

• Each key in the keypad has a distinct identity.
• The feature is applicable for all the gates but each has its unique different password.
• The system is fully controlled by the 8-bit microcontroller.
• It has multiple door control with a different authenticated password to open.
