Cities, buildings and factories have become more intelligent, driving the need for more robust sensing. In recent years, millimetre-wave (mmWave) sensors have gained a lot of traction due to their ability to sense the range, velocity and angle of objects in a scene. This paper from Texas Instruments, discusses choosing 60GHz mmWave sensors over 24GHz.
mmWave sensors use radio frequency (RF) sensing rather than light or sound, which offers unique advantages because the sensors can detect people and objects through a variety of materials such as glass and drywall. These sensors can also operate even when environmental factors such as smoke, rain and low-light conditions are present.
Such robustness enables strong performance in both indoor and outdoor applications, including displacement transmitters, safety guards, lighting control and intelligent transport systems.
