Introduction<\/h2>\n

Staircases are high-risk areas for falls, especially in the dark. PIR sensors can trigger lighting when someone approaches, improving safety and saving energy.<\/p>\n

Applications<\/h2>\n

Automatic Stair Lighting<\/h3>\n

Lights turn on when person approaches staircase, turn off after they pass. Can be zoned to light only the steps being used.<\/p>\n

Fall Detection<\/h3>\n

Detect if someone falls on stairs and trigger alert.<\/p>\n

Direction Detection<\/h3>\n

With multiple sensors, detect whether person is going up or down to control lighting accordingly.<\/p>\n

Sensor Placement on Stairs<\/h2>\n

Top and Bottom of Stairs<\/h3>\n

Detect approach from either end.<\/p>\n

Midway on Landing<\/h3>\n

For fall detection and tracking on long staircases.<\/p>\n

Under Handrail<\/h3>\n

Discreet placement that doesn’t interfere with lighting.<\/p>\n

Lighting Control Logic<\/h2>\n
\/\/ Direction detection logic\nif (topSensor.triggered && !bottomSensor.triggered) {\n    \/\/ Person at top - light staircase from top down\n    lightStaircase(TOP_TO_BOTTOM);\n} else if (bottomSensor.triggered && !topSensor.triggered) {\n    \/\/ Person at bottom - light staircase from bottom up\n    lightStaircase(BOTTOM_TO_TOP);\n}\n<\/code><\/pre>\n
Fall Detection Algorithms<\/h2>\n
Key indicators of a fall on stairs:<\/p>\n
    \n
  • Rapid downward motion (faster than normal walking)<\/li>\n
  • Prolonged inactivity after motion<\/li>\n
  • Detection at unusual height (sensor placed low)<\/li>\n
  • Multiple sensors triggered in quick succession<\/li>\n<\/ul>\n
    Safety Benefits<\/h2>\n
    Well-lit stairs reduce fall risk. Studies show that properly illuminated staircases have 60% fewer accidents.<\/p>\n
    Energy Savings<\/h2>\n
    LED lighting controlled by PIR sensors can reduce stair lighting energy consumption by 80-90% compared to always-on lighting.<\/p>\n
    Case Study: Apartment Building<\/h2>\n
    An apartment building installed PIR-controlled LED strip lighting on staircases. Energy consumption for stair lighting dropped by 90% compared to always-on lighting, and resident satisfaction increased due to responsive lighting.<\/p>\n
    Conclusion<\/h2>\n
    PIR sensors make staircases safer and more energy-efficient. They are a low-cost upgrade for any building, from single-family homes to high-rise apartments.<\/p>\n","protected":false},"excerpt":{"rendered":"
