Photoresistor
noun
A photoresistor is a type of resistor whose resistance decreases with increasing incident light intensity.
The amount of light hitting the photoresistor directly affects its electrical resistance.
Often appears as...
- light sensor circuits
- optical sensors
Usage tips
Neutral
light sensor, light-dependent resistor, variable resistor
