Application of LDR Light dependent resistor is a simple and low cost device. This device is used where there is a need to sense the presence and absence of the required light. These resistors are used as light sensors and LDR applications mainly include alarm locks, street lights, light intensity meter, burglar alarm circuits. For a better understanding of this concept, here we have described one project namely; saving the intensity-controlled streetlight using the LDR.
