Practical motion sensor set: you will receive 3 pieces of motion detectors in black colors, the load of approximately 5W to 100W, and the working voltage is about DC 2.7 V-12V, reliable and reusable for you to useInfrared sensor switch utilizes human motion infrared rays as control signal sources, when one enters the detection field, it will start the controlled load at once.Accurate sensitivity: the smart motion sensor light switch is a digital intelligent automatic control product, which is highly sensitive and reliable to use; When an object or person enters the sensing range, this pir detector can be automatically turned on, and can be automatically delayed off after the person leaves, which can well avoid the situation of not turning off the lightnergy-saving and low heat and low consumption. Motion sensor turns lights ON automatically when motion is detected and OFF after a pre- time delay (5sec to 6minutes).People can enter the sensing range and can be automatically turned on,When people leave, they can automatically delay the shutdown, so as to prevent the conventional lamps from being opened.Colour:blackMaterial:plasticPackage Contents:3 x Automatic motion sensorsOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
