Digital LDR Module

The Digital LDR Module detects the presence and intensity of light. It outputs a high signal when light is detected and a low signal in its absence. The sensitivity of the module can be adjusted via an onboard potentiometer, allowing it to react to different light conditions.

Light Dependent Resistor (LDR)

• Overload Power: Do not exceed the recommended operating voltage of 5V DC to avoid damaging the module.,
• Expose To Extreme Conditions: Avoid exposing the module to extreme environmental conditions that could affect its performance and longevity.

• Adjust Sensitivity: Use the onboard potentiometer to adjust the sensitivity of the module to suit the ambient light conditions of your environment.,
• Mount Securely: Utilize the M3 mounting hole to securely attach the module to an object or surface.,
• Check Power Requirements: Ensure that the module is connected to a power supply between 3.3V and 5V DC.

• Maximum: 15 mA

• Minimum: 3.3V,
• Maximum: 5V

• Do: Connect the Digital Output to a microcontroller unit (MCU) to detect high or low TTL signals, or directly to a relay module to create a photoelectric switch.

• Vcc: Connect to a power supply between 3.3V and 5V DC.,
• Gnd: Connect to the ground of the power supply.
