Description
Features:
| CATEGORY | SPECIFICATIONS |
|---|---|
| Device Type | Photoresistor (Light Dependent Resistor - LDR) |
| Spectral Types | UV light-sensitive, Infrared light-sensitive, Visible light-sensitive photoresistors |
| Working Principle | Resistance changes based on light intensity (photoelectric effect) |
| Dark Current | Current flowing through the device when no light is present under applied voltage |
| Dark Resistance | Resistance value measured in complete darkness (high resistance state) |
| Light Resistance | Resistance value when exposed to light (lower than dark resistance) |
| Sensitivity | Relative change between dark resistance and illuminated resistance |
| Voltage Characteristic | Relationship between applied voltage and photocurrent (photocurrent increases with voltage) |
| Volt-Ampere Curve | Describes photocurrent behavior as applied voltage increases |
| Temperature Coefficient | Sensitivity decreases as temperature increases; higher sensitivity at low temperatures |
| Rated Power | Maximum allowable power dissipation under safe operating conditions |
| Thermal Behavior | Power handling decreases as temperature rises |
| Key Features | Simple structure, wide spectral variants, responsive to light intensity changes |
| Applications | Light sensing systems, automatic lighting, alarms, robotics, environmental light measurement |
