1. Light-sensitive sensors
Devices that detect and measure light intensity or changes in light, often converting the detected information into electrical signals to control equipment automatically.
1.1. Photoelectric sensing devices
Light-sensitive components that detect the presence, absence, or intensity of light and generate electrical signals in response.
Synonyms
- photoelectric cells
- photocells
- light sensors
- photoelectric sensors
- optical sensors
Examples
- The electric eyes measure changes in light intensity throughout the room.
- The machine uses electric eyes to detect objects moving along the production line.
