Understanding Photoresistor Sensors – Light Sensors and Their Uses A Photoresistor or LDR sensor is an important component frequently employed in light-sensing electronic circuits. This special sensor alters its resistance based on the level of light falling on it. When exposed to bright light, its resistance drops, and when in https://vertexrealm008.ja-blog.com/39123142/trending-update-blog-on-sensor-idr
