Light sensors detect the intensity of light in their surroundings. They convert this light energy into electrical signals that can be measured and used for various purposes, such as adjusting the brightness of a display or triggering automated responses in smart devices.
Visible light energy can be sensed by the eyes. The eyes contain light-sensitive cells called photoreceptors that detect visible light waves, which are a form of electromagnetic radiation. This energy is responsible for enabling humans to see colors and perceive the world around them.
Inductive sensors use a magnetic field to detect objects. Capacitive sensors use an electric field. In order to be sensed by an inductive sensor an object must be conductive. This limits suitable targets to metal objects (for the most part). In order to be sensed by a capacitive sensor the target doesn't need to be conductive. A capacitive sensor will react to an object acting as a dielectric material as well as a conductive object. This makes metal and non-metal objects suitable targets.
Robots use light sensors to detect and measure the intensity of light in their environment. This information can help them navigate, avoid obstacles, or identify specific objects. Light sensors can also be used in applications like line following or detecting changes in ambient light conditions.
Traffic lights typically use sensors such as induction loops, infrared sensors, and cameras. These sensors help detect the presence of vehicles and pedestrians at the intersection, allowing the traffic light to change based on the traffic flow.
A photoelectric sensor, or photo eye, is a device used to detect the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. They are used extensively in industrial manufacturing. There are three different functional types: opposed (through beam), retro-reflective, and proximity-sensing (diffused).Electro-optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. They are used in many industrial and consumer applications, for example: Lamps that turn on automatically in response to darkness. Position sensors that activate when an object interrupts a light beam.
so heat can be sensed faster
Stimuli must be sensed in order to produce a response.
There are so many that making a list is impossible. Basically every function, movement, can and is sensed by the sensors.
Light sensors measure the number of photons or the energy of light hitting the sensor.

Light sensors are devices that are designed to detect light. There are several different types and styles of light sensors, each of them unique and having their own specific and useful uses.
Light is sensed by the photoreceptor cells in the retina at the back of the eye. The visual information is then processed and perceived in the brain, specifically in the visual cortex located at the back of the brain.
Visible light energy can be sensed by the eyes. The eyes contain light-sensitive cells called photoreceptors that detect visible light waves, which are a form of electromagnetic radiation. This energy is responsible for enabling humans to see colors and perceive the world around them.
The main sensor used for garaged doors is a infrared line sensor. When the line of sight is broken the sensor is activated. Pressure sensors may additionally be implemented to stop the closing action if opposite pressure is sensed.
Stop light sensors are a loop of wire that is buried in the pavement and controls the traffic light. The sensors are able to detect the traffic that is waiting at the light.
Many things can be sensed by humans - too many to name all of them!Some things that you can sense are visible light, sound within a certain set of frequencies, touch, and taste.
