I was tasked in creating an advanced home security system, however, I didn't want to go with the generic keypad/fob and flashy lighting project, but instead consider real world scenarios that may be detrimental to families.

The advanced home security system was tailored for two distinct scenarios unfolding on separate floors. The initial scenario simulates a home burglary, while the second scenario replicates a tornado, both scenarios which can put homeowners in potentially life threatening situations.

Home Burglary

• Burglar breaks in through the door or window

  • Trips the laser sensing alarm at door or flex sensor at window

  • Begins the advanced intruder detection system

    • Light indicating intrusion through door or window

    • Alarm

    • PSD sensor and Servo to track location of burglar in house

Tornado

The three key signs of tornadoes include dark ominous clouds, heavy rain/hail and exceptionally strong winds. The security system was structured with three corresponding levels, denoted as Level 1, Level 2, and Level 3, aligned with these key signs. A tornado/hurican bunker was implemented as the last lign of defence.

• Level 1: LDR Sensor picks up darkness in sky from the clouds

  • Neopixel lights up first three lights to green

• Level 2: Rain Sensor detects heavy rain

  • Neopixel lights up next three lights to yellow

• Level 3: Flex Sensors on window detect strong winds once windows break open

  • Neopixel lights up next three lights to red, completing the sequence

  • Alarm 

  • Bunker doors remain open until PSD sensor detects all the family members are situated in the bunker, and bunker doors close

The system enters a resting state once any of the three levels is no longer set to high priority. However, indicators for each level remain active until all three levels cease sensing.
