Product Description

1 Channel Light Dependent Resistor Photosensitive Resistance Module

Dark current, dark resistance: photosensitive resistance at a certain applied voltage, when the light is not irradiated when the flowing Current is called dark current.

Applied voltage and dark current ratio as the dark resistance.

Sensitivity: Sensitivity is irradiated by a light-sensitive resistor, the resistance value (dark resistance) when irradiated with light Resistance value (light resistance) the relative change in values.

Volt-ampere characteristic curve. Voltage characteristic curves are used to describe the resistance of the applied voltage and the photosensitive photocurrent relationship, On the photosensitive devices, the light current with applied voltage increases.

Temperature coefficient. Photoelectric effect photoresistor affected by temperature, at a low-temperature portion photoresistor photoelectric Sensitive high sensitivity at high temperatures is low.

Rated power. Photosensitive resistor rated power is allowed for certain lines in the power consumed when the temperature rise High, its power consumption is reduced.


Development  Resources: demo codes, schematics, datasheets, etc

Photodiodes are similar to regular semiconductor diodes except that they may be either exposed (to detect vacuum UV or X-rays) or packaged with a window or optical fibre connection to allow light to reach the sensitive part of the device. Many diodes designed for use especially as a photodiode use a PIN junction rather than a p–n junction, to increase the speed of response. A photodiode is designed to operate in reverse bias.

Photodiode sensors:

It is a form of lightweight sensor that converts light energy into electrical voltage or current. The photodiode is a type of semiconducting device with a PN junction. … The photodiode accepts light energy as input to generate an electric current. It is also called a Photodetector, photo sensor or light detector.
