Photoresistor Detection Photosensitive Light Sensor Module for Light Intensity Sensing and Light-Based Automation Projects
৳65
Description:
The Photoresistor Detection Photosensitive Light Sensor Module is an essential component for projects that require light intensity detection. Utilizing a photoresistor (LDR), this module can sense the level of ambient light and adjust its output accordingly. The sensor operates by changing its resistance based on the amount of light falling on it—higher light levels reduce the resistance, while lower light levels increase it. This feature makes it ideal for light-sensitive applications such as automatic lighting systems, solar power applications, and smart home projects. It's a simple and cost-effective solution for integrating light detection into various DIY electronics projects.
