INS-333x Radar Sensor

Product family: Motion Detector & Touchless Switch
Applications: Building Automation, Motion Sensor, Proximity Detector, Light Control, Alarm System
Functions: Movement, Velocity, Direction
The INS-333x is a 2in1 radar sensor: It combines the functionality of a motion detector with near field presence detection. This offers integrators the possibility to implement and use two different control types with only one radar device. The product can be used as a motion sensor for automation tasks and as a touchless switch. Users trigger a reaction by simply holding or moving the hand in the near field of the antenna (in a distance of less than 10cm), e.g. switching a light off. In a detection range from up to 10m users can automatically activate e.g. the light (motion trigger). The 24GHz Doppler radar also determines information about speed, motion direction and signal strength of objects. It is equipped with three open collector outputs and indicator LEDs: Two of them showing each direction of the detected movement, the other one shows the activation of the proximity switch function.
