In photography, the golden hour is the period of daytime shortly after sunrise or before sunset, during which daylight is redder and softer than when the sun is higher in the sky. The golden hour is also sometimes called the magic hour, especially by cinematographers and photographers.
Proximity sensors are extensively used in manufacturing and industrial automation. They can detect the presence and position of objects on conveyor belts, ensuring smooth production lines and providing additional safety in the case of something unintended ending up on the conveyor belt.
A controller, in a computing context, is a hardware device or a software program that manages or directs the flow of data between two entities. In computing, controllers may be cards, microchips or separate hardware devices for the control of a peripheral device.
Once the photocell is exposed to a certain amount of light, the current flows and the fixture shuts itself off. Then, as the sun goes down in the evening, the current stops, signaling for the fixture to turn on automatically.Full cutoff wall pack

Haint Blue, a Traditional Paint Color with a Haunted History. Whether you are warding off evil spirits, bugs, or cloudy days, haint blue may be for you! Painting porch ceilings blue is a practice originally adopted in the old South, inspired by several myths and superstitions.
One of the things that cause dusk to dawn lights to flicker is that the air pressure around your home creates a powerful magnetic field that can rub off the protective coating on the batteries in your sunshine.
You could use a TV's power LED to detect light levels, and thus adjust screen brightness appropriately. You can even do simple proximity sensing, using an array of LEDs to act as emitters and sensors in turn. You could even use status LEDs on small devices to do bidirectional communication if you were so inclined.
In many cases, a reflex sensor is used to detect an object that moves at a distance in front of a background, such as a sheet of paper, a band or a plate.
