Decide whether you need light with sensor when you purchase the light for your yard or indoor or outdoor lighting: Look at your circumstances and decide if you could use a motion sensor light for safety or convenience.

The sensor is an intelligent induction control device. It uses infrared induction control technology to control the light switch by detecting the movement of the human body and the illuminance of the environment. At the same time, it provides a simple manual control mode, which can conveniently set the environmental illuminance limit of the light start and the continuous lighting time of the light Make presets. Only when the ambient illuminance is lower than the set limit and human activity is detected, the sensor switch can be activated. After the person leaves the sensing area, the light will automatically go out at the set time, ensuring that the light is on when the person comes, and the light is off when the person walks, so as to achieve the effect of energy-saving and energy-saving to the greatest extent. The sensor switch can be installed with ordinary incandescent bulbs and ordinary energy-saving lamps. It is suitable for bathrooms, kitchens, balconies, corridors, stairs, storage rooms, warehouses, garages, and other indoor places that do not require long-term lighting. It can also be used as a family room anti-theft Of light alarm product.

What’s the difference between photocells sensors and motion sensors?

Photocells and motion sensors are electronic devices you can use to manage lamp lighting. These sensors improve the security and safety of your home, automatically turning on lights when it gets dark or they detect motion. They also save energy by automatically turning themselves off when they needn’t. Explore the differences between photocells sensors and motion sensors and find out how these products, along with dimmers and other controls, can enhance your home’s lighting system.


Photocell functions: dusk to dawn

One of the most common functions of photocells sensors is turning outdoor lights on at sunset and off at dawn. Because they sense ambient light levels, photocells automatically adjust to seasonal changes in the day/night cycle and are unaffected by daylight-saving time. Photocells control outdoor lights combine with timers that turn on interior fixtures create the illusion of occupancy when you’re not home, which can deter intruders. Other photocell uses include turning on the parking lot or street lights after dark, adjusting indoor dimmers to compensate for changing natural light levels or switching illuminated business signs on or off.


Motion Sensors

The main difference between photocells and motion sensors is that the former detects changing light levels, and the latter reacts to physical movement. There are two types of motion detectors. Active models emit light, radio, or ultrasonic sound. Movement in the detection area changes the reflected signals and activates the sensor. Some of these devices can even sense motion around corners. Passive motion sensors detect the infrared energy given off by warm objects such as animals or people. When these warm spots move, it triggers the sensor and any connected electrical circuit.

Many motion sensors use a combination of detection methods to provide enhanced coverage and eliminate false positives. Devices designed for outdoor use often include a photocell function that turns the system off during the day, which conserves energy. The adjustable timers built into some sensors let you control how long the attached lights remain active after it detects motion.

Detector functionality

Motion sensors are often used to turn on outdoor lights when they detect movement in their coverage area. They’re also used as energy-saving occupancy sensors in commercial buildings, turning off lights in empty offices. Many of these products have adjustable sensing areas, letting you cover specific locations such as driveways or walking paths without picking up movement from tree branches or nearby streets.


Motion sensor varieties

Most motion sensors designed for outdoor light management connect directly to a 120-volt circuit and control multiple fixtures. Security system sensors are often battery-powered and transmit alerts wirelessly to a base station. Some stand-alone motion sensors have built-in lights, making them easy to install and use almost anywhere.


Bright Ideas for lighting applications

The differences between photocells and motion sensors offer many control options for indoor and outdoor lighting systems. Use a combination photocell and motion sensor to activate security lights around your home, but only after dark. Place a motion sensor and outdoor lights along a sidewalk or garden path to ensure safe footing when walking the dog or taking out the garbage at night.

Ensure decorative light fixtures are always on after dark using a photocell. Combine a lamp, a plug-in photocell, and a traditional light switch to create an automatic light you can turn on only when it’s needed. Use motion sensors with integrated lights to offer free-hand stairway illumination.

Motion sensors and photocells sensors turn on or off based on changing light levels or detected motion. They’re compatible with many different types of light fixtures, and some work with security systems. Save energy and enhance your home’s appearance and safety with these flexible controls.

Passive infrared (PIR)

Passive infrared (PIR) sensors are sensitive to a person’s skin temperature through emitted black-body radiation at mid-infrared wavelengths, in contrast to background objects at room temperature. No energy is emitted from the sensor, thus the name passive infrared. This distinguishes it from the electric eye for instance (not usually considered a motion detector), in which the crossing of a person or vehicle interrupts a visible or infrared beam. These devices can detect objects, people, or animals by picking up one’s infrared radiation.


Motion sensor

A motion detector is an electrical device that uses a sensor to detect nearby motion. Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in a region. They form an important component of security, automated lighting control, home control, energy efficiency, and other useful systems.

An active electronic motion detector contains an optical, microwave, or acoustic sensor, as well as a transmitter. However, a passive contains only a sensor and only senses a signature from the moving object via emission or reflection. Changes in the optical, microwave, or acoustic field in the device’s proximity are interpreted by the electronics based on one of several technologies. Most low-cost motion detectors can detect motion at distances of about 15 feet (4.6 m). Specialized systems are more expensive but have either increased sensitivity or much longer ranges. Tomographic motion detection systems can cover much larger areas because the radio waves it senses are at frequencies that penetrate most walls and obstructions, and are detected in multiple locations.

Motion detectors have found wide use in commercial applications. One common application is activating automatic door openers in businesses and public buildings. Motion sensors are also widely used in lieu of a true occupancy sensor in activating street lights or indoor lights in walkways, such as lobbies and staircases. In such smart lighting systems, energy is conserved by only powering the lights for the duration of a timer, after which the person has presumably left the area. A motion detector may be among the sensors of a burglar alarm that is used to alert the homeowner or security service when it detects the motion of a possible intruder. Such a detector may also trigger a security camera to record the possible intrusion.

Microwave sensor

Based on microwave technology, automatic control, high sensitivity, high reliability, intelligence, humane. The switch unipolar design can directly replace the wall switch, voice-activated switch, touch switch, no need to change the original wiring, easy to use. Don’t leave the sensing range, and can continuously output the high level; left, switch delay automatic load. Can be connected with various types of lamps, fan load, delay, and photosensitive.

Suitable for an incandescent lamp, energy-saving lamps, LED lights, electronic fluorescent lamps, an exhaust fan, and other kinds of loads; is a corridor, stair, toilet, basement, garage lighting switch is the best choice.

Automatic induction: adopts microwave technology, dedicated to detecting human walking changes automatically open, so no firecrackers, barking, Che Ming, noise, performance is better than the sound-control switch and the touch switch.

Automatic exposure: application photosensitive control, daytime or glare not induction, night or can be induced under weak light.

Automatic delay: switch connected in, if a person on the switch within the sensing activity has been switched on. If people leave the sensing range according to finally leave the time before the onset of delay. Fixed delay time:30 seconds

Security and Safety Lighting Systems

Motion detectors are used with lights or systems of lights for safety and security reasons. If a person walks by a monitored area the light will automatically turn on right away. Your security camera will catch that person in a photo or video. Especially in your door of house or yards. led your led yard flood lights to match the motion sensor.

Motion-activated led yards flood lights are the most popular type of light used with a motion sensor. They’re used for security as they light up the outdoor area at night. You can have a system that activates all floodlights around your home and garage when only one sensor is tripped.

For safety purposes, these are helpful and convenient when walking outdoors to a destination in the dark, such as the garage, for example. It can save you money on energy as they’re only turned on as you’re detected. You can turn off the alarm system for these types of uses.

Why Do I Need A Light with Motion Sensors?—-led yard flood lights

Your entire property should have motion sensor coverage so whoever or whatever is out there is promptly frightened away by the activation of your floodlights. If you have a large yard, they can be set up far away from your building so that the authorities are notified before they get to your door or window.

Lights that are high-powered and on all night will take a lot of power and result in huge electricity bills for you and your family. But normal floodlights are constantly on will create a lot of lumens, which means they’re very bright and energy-consuming. These could bother your neighbors at night if continuously on.

Outdoor motion sensor lights only come on when tripped.  By using a motion sensor with your floodlights, you’re only paying for the lumens you need to use, in an emergency situation or when you choose to use them.

With solar-powered lights, you don’t have enough lumens to scare someone away. Plus they’re not going to work all night. To solve your problem, you’ll need a light with a motion detector or motion sensor. For more details, please contact me for led yard floodlights.
