PIR Sensor Activation: Equipped with a sensitive motion detection mechanism, this black occupancy sensor light switch activates lighting and electrical devices upon detecting movement, enhancing convenience and security in your home or office. Customizable Delay Settings: Initiate with the lowest delay setting and adjust to find your preferred sensitivity level and light duration, ranging from 18 to 300 seconds. This feature ensures that the lights remain on just long enough after activation, resetting with each detected motion. Energy Conservation: Designed to promote energy efficiency, this LED motion sensor automatically turns off lights when no movement is detected within the set time. Ideal for installation at heights of 8 feet, it effectively senses motion up to 16 feet away, reducing unnecessary power consumption. Broad Detection Range: With a 120-degree wide sensing angle, this high-sensitivity DC motion sensor is versatile for various applications including entrance, cabinet, and storage room lighting, as well as for enhancing security in advertising spaces. Comprehensive Package: Each package includes three mini PIR motion sensors with a DC coupler cable, ensuring you have sufficient units for multiple installations or replacements. These sensors operate effectively within a voltage range of 5V to 24V and a current up to 5A.
