Construction Usage & Operating Principle of Light Dependent Resistors LDR’s

LDR or Light Dependent Resistor which is also known as photo resistor is a device whose resistivity is a function of the incident electromagnetic radiation. SO we can say that these are light sensitive devices. Other terms which are used for LDR are photo conductors, photo conductive cells or simply photocells.  Light dependent resistor (LDR) or… Read More »
