Understanding Light Dependent Resistors (LDRs) – Photo-Resistors and Their Uses A Photoresistor or photoresistive sensor is an essential component widely used in illumination detection 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 https://creativebase652.activoblog.com/47028417/the-blog-on-sensor-idr
