Simple Security System Using Logic Gates

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

Simple security system using logic gates. Dld project submissing to chowdhury akram hossain aiub. I have complied this list from different resources. 2 are connected as shown in fig. The idea is of this system is that the 4 switches key code switches acts as holding the correct password for unlocking the lock.

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. 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. Security system using xor nor 1.

The output is high only if both of the inputs are high. A burglar alarm system for a bank is to be operative only if a master switch at the police station has been turned on. And gates can be used in a home alarm system. Digital logic design projects list with logic gates for beginners.

Based on this logic gates are named as and gate or gate not gate etc. 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. Logic gates are the basic building blocks of any digital system.

A two input and gate is an electronic logic gate that has two inputs and one output. The relationship between the input and the output is based on a certain logic. Simple password lock system using logic gates digital system miniproject duration. The digital security system circuit.

Output is based on the voltage on pin 5. 1 4 bit password security system using nor xor. Before using this security system make sure that loops shown in fig. 2 shows the proposed wiring diagram for the loops around the premises.

4 bit password security system using xor and nor digital logic design 2. You can create a three input and gate by using two two input and gates for example. Also read the interesting post pull pin security alarm system. Functioning of these circuits is very easy when we will receive.
