You’re asking what is LDR? It stands for Light Dependent Resistor or Photoresistor, which is a passive electronic component, basically a resistor which has a resistance that varies depending of the ...

In this article, we look at the main classes of photoresistor, namely, intrinsic and extrinsic photoresistors. When it comes to photoresistors, there is not a great deal of difference between the ...

This is a very interesting a.c. voltage stabilizer that uses a LDR or photoresistor to stabilize an alternating current (AC). If the voltage increases then the brightness of the light bulb increases ...

[Fjord Carver] brings together an RGB LED and CdS Photoresistor to make a color sensor. Those Cadmium Sulfide lights sensors usually have a very wide swing of resistance when exposed to varying ...

He decided to try and hack together his own single-pixel camera, but this time on the cheap and using an ever simpler component – a photoresistor! His description of the project tickled me ...

b: The on-off ratios (the ratio of conductivity with/without pseudo-sunlight) of the photoresistor devices. The higher the on-off ratio, the better the performance of the photoresistor.
