LDR LIGHT SENSOR MODULE

Description: External 3.3V-5V VCC External GND GND DO digital output interfacea small plate (0 and 1) AO small board analog output interface. Specification : - Detection Range: The detection range of the module varies based on the intensity of light in the environment. It can detect light in a range of 380nm to 750nm. - Operating Voltage: The module operates on a voltage range of 3.3V to 5V. - Working Principle: The LDR sensor is composed of a semiconductor material that changes its resistance as the intensity of light changes. As the intensity of light increases, the resistance of the LDR sensor decreases. The resistor in the module is responsible for providing a constant voltage across the LDR sensor. - Output: The module provides an analog output that varies based on the amount of light detected by the LDR sensor. The output voltage varies between 0V to the operating voltage. - Size and Dimension: The module is compact in size and measures approximately 28mm x 15mm. - Use Case: The LDR Light Sensor Module is widely used in various applications such as street lighting, security systems, automatic window shades, and plant growth monitoring. It is also used in hobby projects that involve robotics, IoT, and home automation.
