Simple Security System Using Logic Gates

It is the nature of an xor gate to output a high 1 signal if the input signals are not the same logic state.

Simple security system using logic gates.

Output is based on the voltage on pin 5. 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. 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. 2 shows the proposed wiring diagram for the loops around the premises.

Security system using xor nor 1. The idea is of this system is that the 4 switches key code switches acts as holding the correct password for unlocking the lock. Also read the interesting post pull pin security alarm system. 2 are connected as shown in fig.

1 shows the circuit of the digital security system while fig. Based on this logic gates are named as and gate or gate not gate etc. And gates can be used in a home alarm system. 6 bit password based security system using logic gates duration.

At the time when power supply is attached to the circuit pin 5 voltage is at zero as loop is unbroken. 4 bit password security system using xor and nor digital logic design 2. 1 4 bit password security system using nor xor. 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.

Dld project submissing to chowdhury akram hossain aiub. Here the inputs for the various sensors placed on the home s. The digital security system circuit. Simple password lock system using logic gates digital system miniproject duration.

Logic gates are the basic building blocks of any digital system. 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 output is high only if both of the inputs are high. Ra r 5 447 views.

The relationship between the input and the output is based on a certain logic. I have complied this list from different resources. Functioning of these circuits is very easy when we will receive. It is an electronic circuit having one or more than one input and only one output.

Before using this security system make sure that loops shown in fig.
