SC1233AR3 24GHz RADAR Sensor

July 23, 2019

 All-in-one RADAR sensor for Entry Motion & 2D Detection

Overview

Easy-to-use, all-in-one 24GHz radar sensor enables entry motion and distance detection without the need for external MCU. The sensor also performs angle detection with light MCU calculations.

Features

  • Easy to Use
    • Reduction of BOM using an "all-in-one" radar sensor package
    • Built-in autonomous entry motion and distance detection function with I2C/SPI connection
      for setting configurations and data acquisition
  • Wide Detection Area with 2D Detection
    • Detection area example: >8m (*2) at front direction, 120 degrees FOV
    • 2RX antennas capable of 2D angle detection with external MCU calculation
  • Suitable for Battery Operation
    • 0.5mW average operating power for human detection applications(*3)
    • After sensor setup & run, MCU can sleep until something detected
