Perfect for Arduino
Used this for a night light project. Very responsive to light changes.
Description
This photoresistor sensor module detects light intensity and functions as a photoelectric switch for electronic projects. It features a sensitive light-dependent resistor capable of triggering signals based on ambient brightness changes. The package includes Dupont cables to facilitate easy connection to microcontrollers or breadboards. Ensure proper pin alignment matching your specific 3-pin or 4-pin version before powering the circuit.
