This project uses a simple LDR that is calibrated against a reference photometer in order to build a digital lux meter. This project uses a simple LDR that is calibrated against a reference photometer ...

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 ...

Photoresistors, also commonly referred to as light-dependent resistors (LDRs), are a class of variables resistors which change their resistance depending on how much light is hitting the resistor.

WARANGAL: Known for his low-cost innovations meant to address issues of people across villages, Mupparapu Raju, a well-known inventor in the Warangal district, has now come back with Light Dependent ...

A recent article in Microsystems & Nanoengineering introduces a low-cost method for optical sensing in microfluidic systems. The researchers used light-dependent resistors (LDRs) as optical detectors ...
