Choosing sensors to enable smarter industrial applications
mmWave sensors use radio frequency (RF) sensing rather than light or sound, which offers 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.
Radar sensing uses multiple RF bands, and each band is governed by regulations that may vary across regions. Most RF sensors use the 24, 60 and 77GHz radio bands. The 77GHz band is common in automotive applications but has restrictions in most global regions for industrial factory, building, and city infrastructure applications, including those that require human/machine interaction.
