What is Proximity Sensor?
Proximity sensors, also known as obstacle detection sensors, are commonly applied in technology to detect metal or non-metal objects. With a range from 1mm to 10mm, these proximity sensors are often used to detect the position of machine components.
Proximity Sensing on SmartphonesNot only used in technology and manufacturing processes, but proximity sensors also play a significant role in various aspects of daily life. Among these, smartphones are one of the most popular and useful applications.
Proximity sensors on phones typically have a range of 2 - 5 cm. Their performance depends on the integrated chipset and the Machine Learning technology employed by the manufacturer.
Classification of Proximity Sensors
Depending on the application environment and user needs, two common types of proximity sensors can be flexibly applied:
Capacitive Technology Proximity Sensor
This technique operates by utilizing the frequency vibrations that high-frequency waves generate on its transmission path to sense and detect objects. Capacitive proximity sensors have the advantage of being less affected by the surrounding environment, but they can only detect metals at short distances.
Capacitive Technology Proximity SensorThe cutting-edge technology of capacitive proximity sensors
Capacitive proximity sensors, also known as dielectric sensors, operate based on the principle of utilizing electrostatics to detect objects. Their major advantage lies in the ability to detect various types of objects, including liquids.
Capacitive proximity sensor technologyThe role of the proximity sensor on your phone
Proximity sensors on phones are an extended function of proximity sensors. They operate using magnetic fields and light waves to detect objects. Consequently, phones can receive information and provide automatic controls.
