SAMSUNG MDRDI304 Motion Detection Sensor
Overview
This product is a module developed for effective human or object recognition using the built-in RADAR sensor. Built-in detectors that allow full autonomous operation of the device. Detector Designed to operate as a Doppler motion sensor from 61 to 61.5 GHz (60.5 to 61 GHz for the Japanese ISM band). The integrated detector in fully autonomous mode provides a digital output indicating movement and direction.
An integrated frequency divider with a kinetic Phase Locked Loop (PLL) provides a Voltage Controlled Oscillator. (VCO) frequency stabilization and Continuous Wave (CW) operation and Distance measurement is possible. This product can be selected in fully autonomous mode, semi-autonomous mode, and various modes through hardware preset pins.
