Detailed explanation-1: -A sensor is a device that detects and responds to some type of input from the physical environment. The input can be light, heat, motion, moisture, pressure or any number of other environmental phenomena.
Detailed explanation-2: -Proximity Sensors detect an object without touching it, and they therefore do not cause abrasion or damage to the object. Devices such as limit switches detect an object by contacting it, but Proximity Sensors are able to detect the presence of the object electrically, without having to touch it.
Detailed explanation-3: -Photoelectric Sensors detect objects, changes in surface conditions, and other items through a variety of optical properties. A Photoelectric Sensor consists primarily of an Emitter for emitting light and a Receiver for receiving light.
Detailed explanation-4: -Ultrasonic sensors use sound waves to detect objects. The working involves a short ultrasonic sound wave being transmitted towards the target. The target reflects back the wave which confirms the presence of the object.
Detailed explanation-5: -Explanation: Capacitive proximity sensor can be used as touch sensor. Capacitive proximity sensors can detect all objects that have a dielectric constant other than air.
