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 ...
This light dependent switch (dark activated switch) was constructed around the operation of a ORP12 photocell where light is the most important factor. Photocell – a type of resistor wherein 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.
