Understanding Photoresistor Sensors – Photo-Resistors and Their Applications A Light Sensor Resistor or LDR sensor is an crucial component commonly utilised in illumination detection electronic circuits. This special sensor alters its resistance based on the amount of light falling on it. When illuminated by bright light, its resistance drops, and https://powerhub87.worldblogged.com/45181660/why-you-need-to-know-about-ldr-resistor-circuit
