Proximity Sensors:
Proximity sensors can detect the presence of an object within predefined distances without any physical contact. They utilise magnetic fields to detect such objects. There is a wide range of proximity sensors available in the market. Let us learn about the popular ones.
Distance Sensors:
Most of the proximity sensors are extensively used as distance sensors. These are also commonly referred to as Range Sensors. The IR and ultrasonics are great assets to calculate distances accurately.
