Proximity Sensors

As mentioned earlier, proximity sensors are sensors that detect the presence or absence of objects within a certain range. These sensors are commonly used in automation systems to detect the presence of objects and to trigger a response, such as activating a motor or solenoid. Proximity sensors can be classified based on the type of technology they use, such as inductive, capacitive, or ultrasonic. Inductive proximity sensors use electromagnetic fields to detect the presence of metal objects, while capacitive sensors use electrostatic fields to detect the presence of non-metal objects. Ultrasonic proximity sensors use high-frequency sound waves to detect the presence of objects.
