A radar system can estimate the angle of a reflected signal within the field of view. Angular estimation is based on the observation that a small change in the distance of an object results in a phase change in the peak of the fast fourier transform (FFT) or Doppler FFT. TI's mmWave solutions can provide 1° angle accuracy and 12° resolution accuracy.
Presence sensing is used to identify when a sensor is near an object of interest. Example use cases include collision avoidance, gesture recognition, open/closed sensing and wake up functionality.
Hall effect sensors are commonly used for measuring the average magnetic flux density of a moving magnet. Magnetic sensors are highly reliable and immune to wear, environmental contaminants and radio frequency (RF) noise. This makes them highly desirable compared to mechanical implementations.

Measure the flow rate and control the flow of gas and liquids. Typical uses include water and gas metering applications.
Hall effect sensors are commonly used in conjunction with a circular ring magnet, which is placed inside the flow meter enclosure, allowing for all of the electronics to be external of the enclosure. The flowing gas or liquid causes the circular ring magnet to rotate and the Hall sensor tracks the movement while providing a signal that can be counted.
