Light Dependent Resistor( LDR photo-resistor) Light Sensor
KSh 10.00
Light Dependent Resistor (LDR) is a light sensing device. It has a resistance change depending on the intensity of light that falls on its surface. It is made up of a high resistive semiconductor.
The resistance is very high in the dark than it is in the daylight. In addition to that, has an output is in the form of analog signal. This signal can easily be calibrated into the intensity of light. Moreover, It is commonly used to automatically turn on a light at a certain light level.
