LDR light detection sensor module 4-pin — analog and digital output, LM393, Arduino compatible EM4100 Reader Pin 3: Output (open collector)This 4 pin LDR (Light Dependent Resistor) sensor module combines a photoresistor with an LM393 voltage comparator to deliver both analog and digital light intensity outputs from a single compact board. The digital threshold is user adjustable via an onboard potentiometer, making it easy to set the exact light level that triggers the digital output no code changes required. It is compatible with Arduino, ESP32, Raspberry Pi, and any 3. 3V or 5V
