An LED is an electircal component which converts electrical energy into light energy whereas an LDR uses light to complete the circuit and maintain the flow of current.
A photoresistor, light dependent resistor (LDR) or cadmium sulfide (CdS) cell is a resistor whose resistancedecreases with increasing incident light intensity. It can also be referred to as a photoconductor.Applications:camera light meters, street lights, clock radios, alarms, and outdoor clocks
Cadmium Sulphide (CdS), Cadmium Selenide (CdSe), Selenium, etc.
No i dont think so!
automatic
Basically, ETC
this is the symbol for ldr
An LDR is a Light dependent resistor.
LDR refers to Light Dependent Resistor.
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.

The symbol for LDR Holding Corporation in NASDAQ is: LDRH.
Light Dependent Resistor LDR also means long distance relationship.
LDR Holding Corporation (LDRH) had its IPO in 2013.
