“The LDR Sensor Module is an easy-to-use component that measures light intensity. It uses a photo-resistor that changes its resistance based on the light hitting its surface. The module is equipped with an LM393 voltage comparator, providing a clean, stable digital signal (0 and 1) and a linear analog output for precise light measurements.
Key Features:
-
Dual Output: Provides both Digital (DO) for simple threshold triggers and Analog (AO) for real-time intensity readings.
-
Adjustable Sensitivity: Built-in potentiometer to set the specific light level at which the digital output triggers.
-
Stable Signal: Clean output wave-form with a driving ability of more than 15mA.
-
Indicator LEDs: Features a power indicator and a digital switch output indicator.”
