Understanding LDR Sensors – Photo-Resistors and Their Uses A Light Sensor Resistor or photoresistive sensor is an essential component widely used in light-sensing 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://ultradomain541.pages10.com/the-must-know-details-and-updates-on-sensor-idr-74216933
