Description:
The Photosensitive Resistance Sensor Module, featuring the LM393 comparator and a Light Dependent Resistor (LDR), is designed to detect ambient light intensity. This module provides digital and analog outputs, making it versatile for applications such as automatic lighting systems, light-activated alarms, and electronic projects requiring light-sensing capabilities. The onboard potentiometer allows users to adjust the sensitivity threshold, enabling precise control over the digital output toggles at the light level.
Operating at a voltage range of 3.3V to 5V, the module is compatible with a wide array of microcontrollers, including Arduino and Raspberry Pi. The digital output (DO) provides a binary signal indicating whether the light intensity is above or below the set threshold, while the analog output (AO) offers a continuous voltage corresponding to the exact light level detected. This dual-output functionality enhances the module’s adaptability in projects requiring both simple light detection and precise light measurement.
