Motion Detection Radar

SMR-313 Radar Sensor

Product family: SMT mountable K-Band Movement Sensor
Applications: Security applications, industrial applications
Functions: Movement, Velocity, Direction
The SMR-313 is a simple radar-based motion detector which determines the speed and direction of moving objects. The small product design makes it possible to integrate the radar sensor even in devices with little space like light switches. It is used for various automation tasks for industrial, home and security applications. The product fits for standard SMT mounting process and will be delivered on Tape & Reel. It also offers a low duty-cycle pulse mode. This capability aids power consumption in low-power applications. The antenna design of the SMR-313 offers a wide field of view.
The InnoSent SMR-Series consists of four product variants.
The SMR 3x3 are CW radar modulations for detection of velocity and motion direction. The SMR-333 is also a CW radar module but comes with a different antenna pattern for a narrow field of view.
The SMR 3x4 uses FMCW radar modulation and additionally detects presence and distance of objects. The SMR-Series does not include signal processing.
