Understanding LDR Sensors – Photo-Resistors and Their Uses A Light Sensor Resistor or photoresistive sensor is an crucial component widely used in light-sensing electronic circuits. This special sensor varies its resistance based on the amount of light falling on it. When illuminated by bright light, its resistance reduces, and when https://elitecircle74.bligblogging.com/39608817/the-must-know-details-and-updates-on-ldr-price
