Photoelectric detectors are best used for detecting smoke and fire in various settings such as homes, offices, and public buildings. These detectors work by detecting the presence of smoke particles in the air, triggering an alarm and allowing prompt action to be taken. They are particularly effective in detecting smoldering fires, which may produce more smoke before flames are visible.

Created the theory of relativity and explained the photoelectric effect
The photoelectric effect, for which he won his Nobel Prize, and the Theory of General Relativity.
He failed math in high school but later went on to postulate the theory of relativity, and he got the Nobel prize for his work on the photoelectric effect.
Just one - 1921 Nobel prize (physics). Curiously, rather than receiving an award for his more famous work on relativity, he won it for his work on the photoelectric effect, which was responsible, in part at least, for the development of quantum theory. It is arguable that, given the work that had been done previously by the likes of, for example, Lorentz, relativity was a theory waiting to happen, whereas the photoelectric effect was much more novel and far-reaching in its effects.
The first smoke detectors are based on optical principles - photoelectric detectors.
Photoelectric detectors are more sensitive to slow, smoldering fires
There are two smoke-sensing technologies commonly used in residential smoke detectors: photoelectric and ionization

Silicon is my best guess
No, ionization and photoelectric smoke detectors should not be interconnected because they use different technologies to detect fires and may not detect all types of fires equally. It is recommended to have a combination of both types of detectors within a home for comprehensive fire detection coverage.
The smoke detectors use the photoelectric effect or a sensor based on the ionization differences between smoke and air.
Smoke detectors typically use either ionization or photoelectric technology to detect smoke. Ionization detectors contain a small amount of radioactive material that ionizes the air, while photoelectric detectors use a light beam that, when disrupted by smoke particles, triggers the alarm. When smoke particles enter the detector, they interrupt the electrical current or light beam, which signals the alarm to sound.
The best radar detectors on the market are made by Beltronics. Beltronics is a leading manufacturer of the Vector, Professional, and Express radar and laser detectors.
Beltronics offers the best performing radar and laser detectors on the road, including the Professional Series models.
Photoelectric imaging is a process that converts light into an electric signal for capturing visual images. It is typically done using sensors or detectors that respond to light by generating an electrical current proportional to the intensity of the light. This electrical signal is then processed to create a digital image.
