Photoresistor Sensor LDR 8mm 3Pin

From the shop's description

Photoresistor Sensor LDR 8mm 3Pin The Photoresistor Sensor LDR 8mm 3Pin is a compact photoresistor module designed to detect ambient light levels and convert them into electrical signals, Photoresistor Sensor typically ranges around 5kΩ to 10kΩ in bright light (10 Lux) and can rise to over 1MΩ in darkness. Featuring an 8mm light-dependent resistor (LDR), it changes resistance based on the intensity of light—low resistance in bright light and high resistance in darkness. This module includes three pins: VCC, GND, and OUT, making it easy to interface with microcontrollers such as Arduino or Raspberry Pi. It is commonly used in automatic lighting systems, solar garden lights, light-activated alarms, and smart home applications. Its small size and ease of use make it ideal for beginner and advanced electronics projects involving light detection and automation. Features 8mm light-dependent resistor (LDR) for ambient light detection. 3-pin interface: VCC, GND, and digital OUT for easy connectivity. Wide operating voltage: Typically 3.3V to 5V, suitable for most microcontrollers. Digital output signal based on light intensity threshold. Adjustable sensitivity via onboard potentiometer. High sensitivity to visible light. Compact and lightweight design. Quick response to changes in light. Low power consumption, ideal for battery-powered systems. Compatible with Arduino, Raspberry Pi, and other development boards. Ideal for light-activated systems, alarms, and smart lighting controls.
