2. Introduction
CDM324D is single channel CW Doppler Radar sensor. It has high sensitivity and low cost advantage to use widely in field of security, and intelligent control, human detection and smart industry and other fields. It has planar microstrip antenna, and low working voltage (3.3V) and tiny power consumption. Also embed 2stage Bandpass amplifier and IF sync switch circuit with pulsed operation. The module has always maintained a unique advantage in the movement and intelligent control of close-range detection targets
