Password Based Security Using Raspberry Pi Pico And GSM Alert

DOWNLOAD ABSTRACT

AIM:

Design and Development of Password based security using Raspberry Pi pico and GSM alert.

PURPOSE:

Security systems are widely used for so many applications. Keypad type password based security systems are inexpensive and user friendly to use. But alerts and notification kind of features need to add then it becomes more smart and secure. We can send alerts through GSM SMS when anyone access system with keypad. To do this we are using raspberry pi pico as microcontroller and GSM modem for message sending. The proposed project title is password based security using raspberry pi and GSM module.

DESCRIPTION:

GSM modem (SIM800C) interfaced with raspberry pi pico through serial port. With 9600 baud rate both will communicate together.  GSM modem works based on AT commands and AT commands protocol implemented in pi pico with the help of firmware. Keypad connected with pi pico digital pins.

WORKING:

DC gear motor is like load. Here we are accessing motor with password. There are two passwords, one is for ON and another one is for OFF the load. User has to enter password through keypad. If password is correct then motor will be ON and OFF based on password between two. If password is incorrect then buzzer will ON. SMS will send if password correct or incorrect. 16×2 LCD display will helps us to see all operational data.
