A light-dependent resistor (LDR) sensor module for detecting light levels in your projects. The resistance changes with light intensity—decreasing in bright light and increasing in darkness—making it perfect for light-activated switches and automatic lighting systems. Features both digital and analog outputs, allowing you to detect light/dark thresholds or measure precise light levels. Compatible with Arduino, Raspberry Pi, micro:bit, and other microcontrollers. Key Features LDR Sensor – Resistance varies with light intensity Dual Output – Digital (DO) and analog (AO) outputs Adjustable Threshold – Onboard potentiometer for digital trigger level 3.3V Compatible – Works with micro:bit and 3.3V systems 4-Pin Interface – Simple connection to microcontrollers Pin Configuration VCC: 3.3V power supply GND: Ground reference DO: Digital output (high/low based on threshold) AO: Analog output (proportional to light level) Ideal For Light-activated switches Automatic lighting systems Day/night detection Light level monitoring Arduino and micro:bit projects Package Contents 1× Light-dependent Resistor Sensor Module Show more
