π 5mm LDR Sensor by ekastore β Light Dependent Resistor (Photoresistor)
Simplify your light-based automation with the 5mm LDR Sensor by ekastore β a compact and reliable photoresistor that reacts to changes in ambient light by varying its resistance. As brightness increases, resistance drops; as darkness falls, resistance rises β making it perfect for detecting day/night conditions in analog circuits.
Ideal for students, makers, and hobbyists, this LDR is a fundamental component in DIY light-sensitive projects like automatic lamps, solar trackers, and smart lighting systems.
