Understanding LDR Sensors – Photo-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 amount of light falling on it. When subjected to bright light, its resistance drops, and when https://reliablegateway10.bloggactif.com/40323965/social-network-trending-updates-on-sensor-idr
