Light Dependent Resistor( LDR photo-resistor) Light Sensor
KSh 50.00
Light Dependent Resistor (LDR) is a light sensing device. Its resistance change depending on the intensity of light that falls on its surface.
Description
Light Dependent Resistor (LDR) is a light sensing device. Its resistance change depending on the intensity of light that falls on its surface. In addition, it is made up of a high resistive semiconductor. Has very high resistance in the dark than it is in the daylight.
Also, it gives output is in the form of analog signal. Hence, the signal can easily be calibrated into the intensity of light. Commonly used to automatically turn on a light at a certain light level.
