Wide-Angle Detection: 120-degree cone angle detection range. High and stable sensitivity, effectively saving you energy and money, and improving efficiency. Using a PIR motion sensor, it can detect human motion by detecting infrared rays emitted by the human body..Intelligent Perception: It will automatically delay to turn off after the person leaves. The built-in temperature compensation chip reduces the impact sensing distance from the temperature. Please note that new and old types of this product will be sent randomly and make sure you don't mind before ordering..USB Port: Make it convenient and simple to stand by. Power through a mobile phone, charging library or other device with a USB port, the output voltage is equal to the input voltage, low power consumption. The working voltage of the infrared sensor is 5V-24V, the output current is 2A, and the passive induction method is adopted..Widely Applicable: Switches using PIR infrared motion sensor detectors can be used in corridors, bathrooms, basements, warehouses, garages and other locations for automatic control functions. The sensor can be triggered continuously, and the sensing distance is 5-7 meters..Service Guarantee: Welcome to ask for any questions during the use of the product. We will reply to you as soon as possible to help you solve the problem. If there is a quality problem, please do not need to worry too much, we will deal with it immediately and refund you in full.
