Light sensor is one of the most common sensors. The kinds are diverse, such as photoelectric tube, photomultiplier tube, photosensitive resistor, photosensitive triode, solar cell, infrared sensor, etc.
First, ldr SensorIdr sensor is a special resistor made of semiconductor materials such as sulfide or selenide barrier. It is also coated with moisture-proof resin and has photoconductive effect.
Idr sensors are sensitive to light sticking. The stronger the light, the smaller the resistance value; the darker the light, the greater the resistance value.
Idr sensor is a kind of special resistor made of special material, which has a rapid decrease of resistance value under the irradiation of specific wavelengths.
The working principle of idr sensors is based on internal photoelectric effect. Ldr sensor is formed by installing electrode leads at both ends of a semiconductor photosensitive material and encapsulating them in a shell with a transparent window.
