More and more end equipment start to use proximity sensors to detecting the presence of nearby objects without physical contact by using electromagnetic fields, light or sound, e.g. major appliances, cell phones, robot and so on. There are many types, each suited to specific applications and environments. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor targets demand different sensors. By analyzing the basic principle of different types of sensor, comparison result with advantages and disadvantages can be achieved.
