This motion sensor uses a PIR detector to sense infrared radiation from people and automatically controls lighting for hands operation and energy savings. Key benefits Reliable automatic control: Detects human motion and turns lights on when someone enters the area, then turns them off after motion stops to save energy. Stable, sensitive detection: Builtin temperature compensation chip minimizes the effect of temperature on detection distance for consistent performance. Wide detection coverage: 120 degree cone angle detection range provides broad area monitoring. Simple USB power: Powered from any standard USB output such as a mobile phone charger, power bank, or USB port on other devices for easy installation and standby use. Low power operation: Output voltage matches the input voltage, keeping power consumption low and eliminating complex power conversion. Key attributes Function: Passive infrared motion detection with automatic on/off control. Compatibility: Works with USB power sources including mobile phone chargers, charging banks, and USBequipped devices. Performance: sensitivity and stable response across typical indoor temperature variations. Connectivity: USB port for convenient and widely available power options. Typical applications Hallways and corridors: Provide automatic lighting for safer passage during night or low light conditions, with lights turning off when areas are unoccupied. Bathrooms and basements: Hands activation for convenience and energy efficiency in spaces where manual switching is inconvenient. Garages and storage areas: Motion activated lighting improves visibility and reduces unnecessary energy use in infrequently accessed spaces. Practical advantages Easy to integrate into existing USBpowered lighting setups without special power supplies. Reduces wasted energy by ensuring lights are only on when needed. Stable operation in different ambient temperatures for dependable detection. This PIR motion sensor is suited for motion activated lighting in corridors, bathrooms, basements, warehouses, garages and other indoor locations where automatic, low power lighting control is desired.
