mmWave IWR – Automated doors & gates

bitfinex www.xingyunzhuwang.com Discover

TI 60-GHz mmWave sensors for industrial applications enable intelligent and energy efficient operation of automated doors and gates. mmWave makes doors smarter by using position and velocity information of moving objects to make real time decisions. TI mmWave sensors also use onboard? rocessing to avoid false detection of people or vehicles that are not intending to move towards a particular entrance. Cover multiple lanes, gates, or a large area of interest by taking advantage of the sensor’s wide field of view. The sensor’s robust performance is maintained in a variety of? environmental conditions such as? rain, fog, smoke, or bright sunlight. TI’s new Antenna on Package (AoP) small form factor and simplified design allows seamless integration in automated door and gate applications while still covering a wide field of view for safe and convenient door operation.

Application
Automated doors & gates
Benefits

-Leverage accuracy of position and velocity information in all environmental conditions to eliminate false detections

-Intelligently track multiple people and cover multiple lanes/doors with a single sensor’s integrated DSP

-Classify between vehicles vs. non-vehicles for smart parking barrier operation
