5mm LDR Sensor

JOD0.20
No tax

5mm light-dependent resistor (LDR) for detecting light intensity. Ideal for automatic lighting, Arduino projects, and DIY electronics.

Overview:
The 5mm LDR Sensor, also known as a photoresistor, changes its resistance based on the amount of light it receives. In bright light, its resistance drops, while in darkness, the resistance increases significantly. This property makes it useful for building light-sensitive circuits, such as automatic lighting controls, alarms, and brightness detection systems. Its compact 5mm size makes it easy to integrate into various projects and breadboards.

Specifications:

  • Type: Light Dependent Resistor (Photoresistor)
