Simple Security System Using Logic Gates

Here the inputs for the various sensors placed on the home s.

Simple security system using logic gates.

The idea is of this system is that the 4 switches key code switches acts as holding the correct password for unlocking the lock. Dld project submissing to chowdhury akram hossain aiub. Also read the interesting post pull pin security alarm system. Subject to this condition the alarm will ring if the vault door is disturbed in any way or if the door to the bank is opened unless a special switch is first operated by the security guard s key.

It is an electronic circuit having one or more than one input and only one output. Simple password lock system using logic gates digital system miniproject duration. Logic gates are the basic building blocks of any digital system. 1 4 bit password security system using nor xor.

2 shows the proposed wiring diagram for the loops around the premises. Output is based on the voltage on pin 5. Based on this logic gates are named as and gate or gate not gate etc. Digital logic design projects list with logic gates for beginners.

2 are connected as shown in fig. A burglar alarm system for a bank is to be operative only if a master switch at the police station has been turned on. The digital security system circuit. The output is high only if both of the inputs are high.

And gates can be used in a home alarm system. This is a complete list of digital logic design projects for those who want to learn about digital logic circuit and want to design digital logic circuit for their project. Security system using xor nor 1. 6 bit password based security system using logic gates duration.

A two input and gate is an electronic logic gate that has two inputs and one output. Functioning of these circuits is very easy when we will receive. Again the purpose of the experiment is not to make a real security system but merely to introduce you to the principle of xor gate code comparison. The relationship between the input and the output is based on a certain logic.

1 shows the circuit of the digital security system while fig. It is the nature of an xor gate to output a high 1 signal if the input signals are not the same logic state. 4 bit password security system using xor and nor digital logic design 2. I have complied this list from different resources.
