Burglar Alarm Logic Gates

This experiement implements burglar alarm using TINION kit. That alarm works on the logic of A N D gate.

Because the circuits are simple and the logic gates are reliable and mass produced the circuits are reliable.

Burglar alarm logic gates. It uses AND Gate Clock Photo sensor. Picture of our Burglar Alarm project This circuit uses a popular timer IC which is 555. The switch is closed or the light is on one of the inputs is LOW the output is HIGH and the buzzer sounds.

When the switch is closed one input of the NAND gate is LOW. Resistors capacitor along with transistor and relay which is used to save your important things from robbery with the help of this easy circuit. 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.

If the circuit detects a change in the condition of a sensor the alarm sounds with a time. Once the alarm is set if any of the doors or windows are opened the alarm will sound. Speaker to produce Police.

This is an example of which type of Logic. The alarm protects the front and back doors and six windows. B Freezer warning.

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 burglar alarm will go off if either the door or the window or both are opened. This means that if either of these things happen ie.

13092019 Applications of Logic gates. Logic gates almost have its applications in any digital circuit. Applications of the NAND gate a Burglar alarm.

OR gates have been used. When the LDR is in the light the other input is LOW. Most probably we all heard about Burglar alarm.

Sound the alarm if the manual lever. What logic gate is this. IC 555 is connected as comparator with pin 6 connected with positive supply the output goes high-1 when the trigger pin 2 is at lower than 13 level of the supply voltage conversely the output goes low-0 when it is above 13.

The TIMER allows the house owner to enter the house by either the front or back door and turn of the alarm system before. Problems on Logic Gates. Below is the logic circuit for a simple house alarm.

Sound the alarm if smoke it detected. Thats why most modern burglar alarms incorporate another piece into the circuit -- the control box. When the ONOFF switch is open the device does not work.

For details about the implemen. Means when both the person sensor and. Using Logic Gates to Make a Light Activated Burglar Alarm.

This intruder alarm or burglar alarm circuit is based on PIR sensor UM3561 and Speaker. It is to explain AND Logic. It produces a warning beep when someone tries to unlock the lock.

The control box is hooked up to one or more alarm circuits but it also has its own power supply. It monitors the circuits and sounds the alarm when they are. It is a device that we used in our houses to protect it from thieves.

Nowadays Electronics finds a large space in daily life applications. Get a quick overview of Problems on Logic Gates from Problems on Logic Gates in just 3 minutes. Simple circuits made of up the different types of logic gates NOT OR AND NOR NAND XOR XNOR can be used to perform simple and useful tasks.

The NAND Gate has two inputs when both of them are high the output is low so tie both the inputs to 5v with the same wire and input terminals also connected with a 1k ohm to ground The input wire should be connected to a 5v DC source. Two door sensors can be connected to the circuit in NO or NC configuration. 12122015 Burglar alarm system is an important part of home security systems.

PIR sensor used here to detect body motion and UM3561. When the switch is closed one input of the NAND gate is LOW. The basic building block of this circuit is CD4011 along with some other components viz.

When you close the ONOff switch the burglar alarm starts working with a time dalay given by the C5 capacitor. 08092015 Luggage Security Alarm Circuit Description.
