How do you measure light intencity?
Measure Light Intensity using Light Dependent Resistor (LDR) The resistance of the Light Dependent Resistor (LDR) varies according to the amount of light that falls on it. The relationship between the resistance RL and light intensity Lux for a typical LDR is RL = 500 / Lux Kohm With the LDR connected to 5V through a 3.3K resistor, the output voltage of the LDR is Vo = 5*RL / (RL+3.3) Reworking the equation, we obtain the light intensity Lux = (2500/Vo - 500)/3.3 For a low cost LDR, at the same light intensity, the part to part variation in resistance can be as high as 50%. Therefore such a low cost LDR is seldom used for measuring light intensity but more for light presence/absence detection.
What is the function of a light dependent resistor?
The resistance of LDR increases when light is not available (or is limited). And the resistance drops when Light is abundant.This principle can be used in proximity detectors where one or more light source(s) is/are active. When a person / object comes in proximity of the source, the light gets reflected from the object-surface & can now be received by LDR. So due to proximity of the object, resistance of LDR changes - this can be used to trigger different actions like open the door, trigger a motor. Fire an alarm. etc.Resistance of LDR varies according to intensity of incident light over it,It is used in street light to detect day/night and turn on/off the street light automatically
