The working principle of a photocell can depend on the occurrence of electrical resistance & the effect of photoelectric. This can be used to change light energy into electrical energy. When the emitter terminal is connected to the negative (-ve) terminal & collector terminal is connected to the positive (+ve) terminal of a battery.
The working principle of the lux meter is based on the relationship between luminous flux and surface area. Luminous flux is the total optical power emitted by the light source, usually expressed in lumens. Surface area is the area of the area illuminated by light, usually expressed in square meters.
Photodetector or Sensor: The photodetector, which transforms light into an electrical signal and is typically a photodiode or a photoresistor, is the brains behind the luxmeter. Because of its sensitivity to light intensity, the photodetector generates a voltage or current in direct proportion to the amount of light it receives.
Photo Lux Meters: Photo lux meters measure light intensity using a photodiode or other light-sensitive element. Photo lux meters are used in a wide range of applications such as photography, mapping, laboratory research, and more.
The exposure meter consists of a photo-electric cell with a sensitive milliammeter and battery connected in series to it. The photoelectric current produced in the cell is directly proportional to the intensity of light. If deflection in the milliammeter is small the photoelectric current is small. It indicates that the intensity of light is small.
Selecting lux meters or light measurement device requires certain performance specifications, including photocell, illumination range, Lux resolution, operating temperature, and foot-candle resolution. Special features include low battery Indicators, low voltage, alarms, remote light sensors, built-in memory, auto power-off, zero function, etc.
