Motion Sensor Indoor Lighting PIR Occupancy Sensor Switch 200w Wall mounting auto on/Off Lights, Presence Detection

Product Information

A passive infrared sensor detects the infrared light emitted by a warm object using passive infrared technology. item specification -- distance: 2~12 meters (adjustable); detection angle: ≤160°; time-delay: 5sec~10min(adjustable); recommended installation height: 1.5~4m. wire connection instruction: brown wire: live input, red wire: live output, blue wire: common neutral. Simple things like air blowing in close proximity or a rodent moving across the floor can still set off your alarm. Infrared motion sensors are typically straightforward to install. Before installation, however, it is important to familiarise yourself with the particular sensor's range. This will help you to plan an effective coverage system and ensure the entire area that needs covering will be monitored.

PIR sensor-based alarms can be designed to ignore certain shapes of moving objects, or only detect motion above a certain height. This makes them suitable for households that have pets, allowing you to set the alarm before leaving the house in the day without worrying that it will be triggered by your cat or dog moving about. Radiation is produced by all objects that have a temperature greater than absolute zero. This energy is expressed in the form of heat energy. Because heat radiates as infrared wavelengths, much of this radiation is not visible to the human eye, however it can be detected by electronic instruments that have been specifically constructed for this purpose. Motion detector with superimposed beam pattern. The length of the beams is a measure of the detectors sensitivity in that direction.The qwyeuro advantage:high-quality switches specially designed for the home, the lights come on when people come, and the lights go off when people walk off, reducing energy waste motion sensor outdoor -- the pir sensor adopts infrared body motion induction technology, which can achieve intelligent control and energy saving. recommended that the product is installed by professional electrician. The PIR sensor is typically mounted on a printed circuit board containing the necessary electronics required to interpret the signals from the sensor itself. The complete assembly is usually contained within a housing, mounted in a location where the sensor can cover the area to be monitored.

PIR-based motion detector edit A PIR motion detector used to control an outdoor, automatic light. A camera trap with PIR motion detector. An indoor light switch equipped with PIR-based occupancy sensor [1]A PIR-based motion detector is used to sense movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically activated lighting systems. Manufacturers recommend careful placement of their products to prevent false alarms (i.e., any detection not caused by an intruder).

Time-delay is added continually: when it receives the second induction signals after the first induction, it will compute time once more on the rest of the first time-delay basic (set time). time-delay adjustment: it can be set according to the consumer’s desire. the minimum time is 10sec±3sec. the maximum is 7min±2min.It is also recommended that the PIR not be placed in such a position that an HVAC vent would blow hot or cold air onto the surface of the plastic which covers the housing's window. Although air has very low emissivity (emits very small amounts of infrared energy), the air blowing on the plastic window cover could change the plastic's temperature enough to trigger a false alarm. Avoid installing sensors near radiators and air vents, for example, as temperature changes could impact reliability or result in a false alarm
