Light Sensor Fixed Resistor φ4 Series for Photoelectric Control


Senba Sensing Technology Co.,Ltd., was founded in 2005, which is focus on the photoelectric components, such as light dependent sensor. Photosensitive resistance is the resistance of a semiconductor material, the conductivity change with light intensity varies.The use of this feature will work made of different shapes and light-receiving area of the photosensitive resistance.

Camera shutter control

LDRs can be used to control the shutter speed on a camera. The LDR would be used to measure the light intensity which then adjusts the camera shutter speed to the appropriate level.
