What is a Photoresistor? Types, construction, working, characteristics and applications of Photoresistor …
As there exist some photoresistors that do not respond to a certain range of light signal wavelength. The variation in resistance is done in about 8 to 12 ms after the incidence of radiation. However, greater than 1 s is needed for the resistance to increase to a higher value in case of less intensity of light.

How to calibrate LDRs (photoresistors)?
Hi Everybody, i want to build a sun tracking system. I want to do this with four LDRs (photoresistors) as light sensor (2 for x-axis and 2 for y-axis) and two servo motors (1 for x-axis and 1 for y-axis). I`ve bought four LDRs an unfortunatelly all four give me other results (resistance) wenn I test them with the same light source. Do You have any …
