This PIR infrared motion sensor switch is designed for LED motion lights and LED strip installations, combining reliable human presence detection with USBpowered convenience. It detects bodyemitted infrared within a 120degree cone and keeps connected LEDs on while motion is present, then automatically turns them off after the adjustable delay to reduce unnecessary power use. Key benefits Accurate PIR detection: Passive infrared sensing with a 120degree detection angle and 5 to 7 meter range for consistent activation of LED fixtures when people enter the sensing zone. Energy saving by automatic timing: Builtin timing circuit keeps lights on only while needed. Default delay is 15 seconds and is adjustable to suit different spaces. Simple USB power: Operates from any 5 V to 24 V DC USB source such as a mobile charger, power bank, computer, or notebook, avoiding complex wiring. Stable performance: Includes a temperature compensation chip for reliable operation across the working temperature range of 15 C to 38 C. Compact and compatible: Small footprint (approx. 5 x 2.6 x 2.2 cm) and 2 A output current makes it suitable for most LED strips and lowpower LED fixtures. Continuous trigger and inductive output: Output remains active while motion is detected, providing steady lighting for corridors, workspaces, and other areas. Typical applications Hallways and stairwells: Automatic on and timed off for hands lighting and reduced energy use. Kitchens and garages: Motionactivated LED strips add convenience for short visits and task lighting. Offices and storage areas: Automate lighting in infrequently used spaces to avoid leaving lights on. What is included 1 PIR motion sensor switch 1 screw for mounting Technical specifications Color: Black (white optional) Operating voltage: 5 V to 24 V DC Output current: 2 A Sensing distance: 5 to 7 m Sensing angle: 120degree cone Induction mode: Passive infrared Trigger mode: Continuous trigger Output mode: Inductive output Time range: Default 15 seconds, adjustable Working temperature: 15 C to 38 C Product size: Approx. 5 x 2.6 x 2.2 cm Power supply options: Mobile phone charger, power bank, computer, notebook Installation notes Power the sensor via a USB power source within the specified voltage range, then connect the sensor output to the LED fixture or LED strip input following standard LED wiring for your setup. Mount the unit where motion of people will cross the detection cone for reliable triggering. Adjust the delay setting as needed for each location.
