Proximity Sensors
Proximity sensors are electronic devices that detect the presence or absence of nearby objects without physical contact, using technologies like infrared, ultrasonic, capacitive, or inductive sensing. They are widely used in automation, robotics, and consumer electronics to enable touchless interactions, object detection, and safety mechanisms. These sensors output a signal when an object enters their detection range, making them essential for non-contact measurement and control applications.
Developers should learn about proximity sensors when building IoT devices, robotics, or automation systems that require object detection, collision avoidance, or user interaction without touch. They are crucial in applications like smartphones (for screen dimming during calls), industrial machinery (for part positioning), and smart home devices (for gesture control), as they provide reliable, non-invasive sensing in various environments.
