Intelligent induction: when a person approaches, the lighting device turns on automatically; when the person leaves, the lighting device turns off automatically. Intelligent delay: after detecting human activity, the switch automatically adds a delay time, with the last detected movement serving as the starting point for the delay. Working mode: once activated, the switch remains on during the delay period if human activity is detected. The device turns off after the delay period ends following the last detected activity. Material: Plastic, Metal Color: White, Green Supply voltage: DC 12V–24V TTL output Delay time: 9 seconds Operating temperature: -15°C to 70°C Infrared sensor: Dual-element, low noise, high sensitivity Size: Approximately 90 x 60 x 45mm (3-35/64 x 2-3/8 x 1-49/64 inches) Weight: Approximately 100g (3-17/32 oz) Note: Avoid rapid environmental changes.
