Description
Features:
| CATEGORY | SPECIFICATIONS |
|---|---|
| Product Type | QRD1113 / QRD1114 Reflective Object Sensor |
| Sensor Type | Phototransistor-based reflective optical sensor |
| Function | Detects presence/absence of nearby objects using reflected infrared light |
| Operating Principle | IR LED emits light → reflection from surface → phototransistor receives reflected signal |
| Output Type | Phototransistor output (analog current response, typically used as digital via circuit) |
| Contact Type | Non-contact sensing |
| Sensing Method | Diffused reflective sensing (no focusing lens required) |
| Package Type | Compact through-hole optical sensor package |
| Features | Daylight filter, compact design, no physical contact sensing |
| Sensitivity Note | Works best with reflective surfaces (e.g., white or high-reflectivity objects) |
| Cross Talk Behavior | Collector current affected by reflected IR intensity |
| Operating Considerations | Sensitive to ambient light and surface reflectivity |
| Applications | Line following robots, object detection, encoder disks, proximity sensing, automation systems |
| Advantage | Simple design, low cost, reliable short-range reflective detection |
Package Includes:
1 x QRD1114 Reflective Object Sensor
