APPLICATION: AUTOMOBILE ALARM SYSTEM

Consider four push buttons switches mounted on the door of an automobile/car. Each input to the NOR gate has a pull-down resistor to pull the inputs to the gate LOW.

Explanation

1.SW0 is to Enable/Disable the Alarm System.

2.When SW0 is at position 'a', regardless of the status of door open/closed, the alarm system is disabled.

3.When SW0 is at position 'b', the alarm system is enabled. Once enabled, and if one or more doors of the car are opened, then one or more inputs go HIGH and produce a LOW output. This sets the alarm ON indicating the open door status.

4.When all auto/car doors are closed, all the input switches are in the position . The inputs to the NOR gate are LLLL and this causes a HIGH output and the alarm is in deactivated mode.

1.when open front door bell switch is 1, back door bell is close 0, doorbell ring
2. when front door bell switch is close 0, back door bell on 1, doorbell ring
3. both doorbell switch close, door bell does not ring
4. both doorbell switch on, door bell ring
operation
if any input or both input are high, the output will be high while both input are low, the output will be low.

-Burglar alarm (and gate)
There is two input in this gate that is from the person sensor and alarm switch. In order for the alarm to turn on, we nees to turn on the alarm switch and if any person walk through the sensor it will turn on. So the combination of high and high input will result the turning on of the alarm.

Inverting NOT gates are single input devices which have an output level that is normally at logic level 1 and goes low to a logic level 0 when its singld input is at logic level 1. In other words it inverts its input signal. The output from a NOT gate only return high again when its is input is a logic level 0 giving us the boolean expression of A'=z

Automatic Fan Control System
- using AND gate

1) When heat detector detect hot=1 and LDR at the daytime=1, the fan will turn ON=1.
2) However, when heat detector detect cold=0, at the nightime=0, the fan will turn OFF=0.
3) If heat detector detect cold=0 at daytime=1, the fan will turn OFF=0.
4) Same goes if heat detector detect hot=1at nightime the fan also will turn OFF=0.

Gate: Nor Gate
Application: Mixer Tank
Operation: 3 input nor gate is used in this mixer tank to control the flow of ingredients that stored in different cylindrical hooper. In addition, one capacitive proximity switch is arranged at the outside each of the bottom of the cylinder to detect the amount of the ingredient. When ingredient below the sensor level, the logic output is HIGH. When the ingredient above the sensor level, the logic output is LOW. When all ingredient comes down to sensor level, all input become HIGH for this nor gate. This output is then connected to the Power Converter and connected to Motor to mix the ingredient because the Nor logic gate activated the motor.

When heat detector is Hot = 1 , smoke detector is smoke = 1 . The siren is ON = 1

When heat detector is Cold = 0 , smoke detector is smoke  = 1  . The siren is ON = 1

When heat detector is Hot = 1 , smoke detector is no smoke = 0. The siren is ON = 1.

When heat detector is cold = 0 , smoke detector is no smoke = 0 . The siren is off = 0

Application: automobile alarm system(NOR GATE)

Consider 4 push buttons=Low(0)

Explanation:

-  the alarm is activate the output of the gate is LOW=0
- When the switch0(Sw0) at a the door remains as open/closed and the alarm is at disabled=0
- While, when the alarm at b it enable SW0=1
- When the other door also open, the input go HIGH=1 and the output is LOW=0
- When the input of SW0,SW1,SW2,SW3,SW4 go LOW=0  LLLL the output is HIGH=1 and the alarm is activate.
