Micro presence sensors are manufactured in diverse types. Every type of micro presence sensor is made to offer distinct advantages in several settings. These types include:
Ultrasonic sensors have the capability to detect objects using sound waves. These sound waves are at a frequency above the range of human hearing. They emit ultrasonic waves, which reflect off prevalent objects in their vicinity. The sensor then computes the distance based on the time it takes for the echo to return. Their ability to discern minute differences in distance renders them suitable for presence detection in dynamic environments. These environments may include manufacturing and robotics.
IR proximity sensors use infrared radiation to detect an object’s presence. Often, these sensors will emit IR radiation and analyze the intensity of the radiation that will be reflected back. If the radiation reflected is at a certain threshold, then the sensor will determine that an object is present. IR proximity sensors have great usage in mobile phones. In mobile phones, they aid in functions like auto-brightness and screen-off. Also, they are employed in security systems and automated lighting.
The presence of capacitive proximity sensors in the environment’s dielectric materials enables them to operate. These sensors can detect both metallic and non-metallic objects. They can detect these objects by analyzing their capacitance. Normally, capacitive sensors will function by establishing an electric field and monitoring changes in capacitance. Such changes occur when an object enters the field. They offer versatility in detecting diverse materials. They include plastics, liquids, and metals. Thus making them suitable for several applications. These applications include level monitoring, and detection of objects in manufacturing.
Microwave sensors detect presence through microwave motion. Also, these sensors are very sensitive to motion. This sensitivity allows them to be used in environments devoid of line-of-sight. Their basic operating procedure involves emitting microwave signals. The signals will then change if the presence of an object interferes with the signal. Its ability to work in challenging environments makes the sensor suitable for outdoor presence detection. Its features allow users to have reliable performance. This performance is crucial in security systems and traffic monitoring.
Micro presence sensors come with myriad features. Here’s a rundown of those features:
