Simple Security System Using Logic Gates

Output is based on the voltage on pin 5.

Simple security system using logic gates.

You can create a three input and gate by using two two input and gates for example. Functioning of these circuits is very easy when we will receive. I have complied this list from different resources. Here the inputs for the various sensors placed on the home s.

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. The output is high only if both of the inputs are high. The idea is of this system is that the 4 switches key code switches acts as holding the correct password for unlocking the lock.

Logic gates are the basic building blocks of any digital system. Ra r 5 447 views. 4 bit password security system using xor and nor digital logic design 2. Security system using xor nor 1.

6 bit password based security system using logic gates duration. Dld project submissing to chowdhury akram hossain aiub. Also read the interesting post pull pin security alarm system. Simple password lock system using logic gates digital system miniproject duration.

At the time when power supply is attached to the circuit pin 5 voltage is at zero as loop is unbroken. 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. 2 shows the proposed wiring diagram for the loops around the premises.

The digital security system circuit. Digital logic design projects list with logic gates for beginners. A burglar alarm system for a bank is to be operative only if a master switch at the police station has been turned on. 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.

1 4 bit password security system using nor xor. And gates can be used in a home alarm system. A two input and gate is an electronic logic gate that has two inputs and one output. 2 are connected as shown in fig.

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.
