Simple Security System Using Logic Gates

1 shows the circuit of the digital security system while fig.

Simple security system using logic gates.

Also read the interesting post pull pin security alarm system. 2 are connected as shown in fig. The output is high only if both of the inputs are high. Based on this logic gates are named as and gate or gate not gate etc.

4 bit password security system using xor and nor digital logic design 2. Digital logic design projects list with logic gates for beginners. Logic gates are the basic building blocks of any digital system. 6 bit password based security system using logic gates duration.

The idea is of this system is that the 4 switches key code switches acts as holding the correct password for unlocking the lock. It is an electronic circuit having one or more than one input and only one output. Dld project submissing to chowdhury akram hossain aiub. 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.

Output is based on the voltage on pin 5. Simple password lock system using logic gates digital system miniproject duration. A burglar alarm system for a bank is to be operative only if a master switch at the police station has been turned on. Before using this security system make sure that loops shown in fig.

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. Ra r 5 447 views. A two input and gate is an electronic logic gate that has two inputs and one output. 1 4 bit password security system using nor xor.

And gates can be used in a home alarm system. It is the nature of an xor gate to output a high 1 signal if the input signals are not the same logic state. You can create a three input and gate by using two two input and gates for example. 2 shows the proposed wiring diagram for the loops around the premises.

Security system using xor nor 1. The digital security system circuit. At the time when power supply is attached to the circuit pin 5 voltage is at zero as loop is unbroken. Functioning of these circuits is very easy when we will receive.

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