No, it requires light within it's field of view whilst it requires physical mechanism to detect.
Most vehicles use a light sensor to detect the ambient light level and automatically turn on the daytime running lamps when it gets dark. This sensor is usually located on the dashboard or near the rearview mirror.
Some times it is the wind that sets them off. I have trees that are close to the house that the sensor is pointed directly at. When the wind blows they trip the motion detector. If the sensitivity is turned up to the top it will pick up small animals. To set this sensitivity do a walk test at night. Get someone to walk past as you turn the sensitivity down. When the sensitivity is down so as not to pick the subject up give it a 1/4 turn to the plus side and that should stop needless tripping.
Telescopes can not detect any radiation for which they were not specifically built. For example, a radio telescope is specifically designed to detect radio waves. Also, telescopes can not detect radiation that is too faint for them. What is too faint depends on the capabilities of the telescope.
An unlit area is typically referred to as a dark or dim area.
A dark matter microscope is used to indirectly detect and study dark matter by analyzing the impact it has on the distribution of visible matter in space. By observing the gravitational effects of dark matter on visible matter, scientists can infer the presence and properties of dark matter particles.
Because motion sensors sense the movement of light, so if its dark, it cant see.
For the newest kind of robot, the light sensor is used to detect the white lines from the dark lines on the nxt this helps your robot follow the lines!!
Installing a motion sensor flood light in your outdoor space can enhance security by deterring intruders, increase safety by illuminating dark areas, and save energy by only turning on when motion is detected.
To effectively utilize a plug-in light sensor to automate lighting in your home, first plug the sensor into an outlet near the light you want to control. Adjust the sensitivity and settings of the sensor to detect when it is dark and trigger the light to turn on. Position the sensor in a location where it can accurately detect changes in light levels. Test the sensor to ensure it is working properly and adjust as needed.
Most vehicles use a light sensor to detect the ambient light level and automatically turn on the daytime running lamps when it gets dark. This sensor is usually located on the dashboard or near the rearview mirror.
You can Buy this swich sensor at electrical lighting shop , this sensor can you fit at the bulb holder and you have to place this in open area.with this sensor your light will switch on when dark in your area.
Installing a ceiling mount motion sensor light in your home can provide increased security by detecting movement and illuminating the area, making it a deterrent for potential intruders. It also offers convenience by automatically turning on and off, saving energy and reducing electricity costs. Additionally, it can enhance safety by lighting up dark areas and preventing accidents.
Using a motion sensor LED shop light has several benefits. It helps save energy by only turning on when motion is detected, providing bright light when needed and saving electricity when not in use. It also enhances safety by illuminating dark areas and can improve convenience by automatically turning on and off.
Installing a ceiling mounted motion sensor light in a room can provide benefits such as increased energy efficiency, convenience, and enhanced security. The light will automatically turn on when motion is detected, saving energy by only illuminating the room when needed. This can also make it easier to navigate the room in the dark without having to fumble for a light switch. Additionally, the motion sensor light can act as a deterrent for potential intruders by lighting up the room when motion is detected, increasing the overall security of the space.

Like humans, dogs cannot see in truly dark conditions, but dogs' eyesight is better at night with minimal light from the moon, stars, or human lighting. They also detect motion much better in general, whereas humans detect color much better, so at night humans are at a disadvantage for color detection but dogs can still see motion easily.
A sensor that is activated by a lack of light (the dark). Usually these can be found in night lights that turn on when the lights are turned out.
