Proximity Sensors:
Proximity sensors are devices that are able to detect the objects without any actual contact with them.Almost in all the cases a plate of glass or plastic separates them.Although you are likely to touch the separating element,but there is no physical contact with the sensor.
This technology also enables adaptive controls, alleviates isolation issues, improves overall application, robustness , generates almost unlimited design flexibility and fosters new functionalities.
Types of proximity sensors:
- Capacitive
- Capacitive displacement sensor
- Doppler effect (sensor based on effect)
- Eddy-current
- Inductive
- Laser range finder
- Magnetic, including Magnetic proximity fuse
- Passive optical (such as charge-coupled devices)
- Passive thermal infrared
- Photocell (reflective)
- Radar
- Reflection of ionising radiation
- Sonar (typically active or passive)
- Ultrasonic sensor(sonar which runs in air)
