Understanding Photoresistor Sensors – Light Dependent Resistors and Their Uses A Light Sensor Resistor or photoresistive sensor is an essential component widely used in photo-sensitive electronic circuits. This special sensor varies its resistance based on the level of light falling on it. When illuminated by bright light, its resistance reduces, https://leadingupdate44.blogdemls.com/38723953/the-blog-on-ldr-price
