5mm 5537 LDR Light Dependent Resistor
5mm 5537 LDR is a 5mm light-dependent resistor with a « 5537 » model number, which is a photosensitive component that changes its electrical resistance based on the intensity of ambient light. Its resistance is high in darkness and decreases as light increases, making it useful for light-sensitive applications like automatic lighting systems, alarms, and light-level detection.

- Light-dependent resistors or photoresistors are a staple of electronics.
- If you need a way to sense the level of ambient light then there is no easier way to do it.
- As the light on the sensor increases then the resistance across the two leads decreases.
