Photo-Resistor Sensor (LDR or Photo-cell)

Regular price LE 5.00

This is a very small light sensor . It is called light sensor or photocell or LDR (light dependent sensor) or photo-resistor. A photocell changes  resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something).
