| Infrared Proximity Sensors | ||
|---|---|---|
| Infrared proximity sensors emit and detect infrared light to determine if an object is within the sensor's range. They are widely used in smartphones, smartwatches, and home automation systems. These sensors are reliable and can detect objects without physical contact. | ||
| 2 | ||
| Ultrasonic Proximity Sensors | ||
|---|---|---|
| Ultrasonic proximity sensors use high-frequency sound waves to detect the presence of objects. They are commonly found in parking sensors, robotic applications, and security systems. These sensors can accurately measure the distance between the sensor and the object. | ||
| 3 | ||
| Capacitive Proximity Sensors | ||
|---|---|---|
| Capacitive proximity sensors detect changes in capacitance to sense the presence of an object. They are often utilized in touch screens, proximity switches, and object detection systems. These sensors can operate through non-metallic materials such as glass or plastic. | ||
| 4 | ||
| Inductive Proximity Sensors | ||
|---|---|---|
| Inductive proximity sensors generate an electromagnetic field to detect metallic objects. They are commonly used in industrial automation, machine control, and conveyor systems. These sensors can detect both ferrous and non-ferrous metals. | ||
