Resistance Photosensitive Sensor Module

Photoelectric Diode Photoresistor Sensor Module

Module description:
Photoresistor is a kind of light controlled variable resistor. Photoresistors have photoconductivity and can be used in photodetectors. Photoresistors are made of high resistance semiconductors. In the dark, the resistance of photoresist can be as high as several megaohms (m Ω), while in sufficient light, the resistance of photoresist can be as low as several hundred ohms. If the incident light on the photoresist exceeds a certain frequency, the photons are absorbed by the semiconductor to the bound electrons enough energy to jump into the conduction band. The resulting free electrons conduct electricity, thereby reducing resistance.

Parameters:
Working voltage: 3.3V~5V
Output type: Digital and analog interfaces. In this module, the stronger the incident light is, the lower the output analog value is.
Interface mode: PH2.0~4P
Module size: 34*25mm
Module weight: 42g
