“In the Instructable, we are going build a Prototype of digital wireless security systems using RF Technology.
The project can be used for security purposes in home, offices, organizations etc.Since it’s built with RF Technology and it’s secured it most cheap and reliable system for small-scale purpose in industries.
Details about the projects:
It can have a range of 100-150 meters but its range can be increased with increase in length in the antenna. It is built with a keypad 44 interfaced with PIC 16F887 microcontroller and LCD._
_Data that is sent through keypad is display onto the LCD 162.When the password is entered it checks the password that is stored in EEPROM memory of the microcontroller.
When the password is correct, it sends the signal wirelessly with the help of RF modules and it can controller anything with the help of controlling circuit.”
