24G microwave module CDM324
CDM324D is a single-channel CW Doppler radar sensor. With its high sensitivity and low cost advantages, it is widely used in security, automatic control, human detection, industrial intelligence and other fields. It has plane microwave band aerial with high applicability, low operating voltage (3.3V) and small power consumption, built-in two-pole band-pass amplifier and pulse-working IF signal synchronous switching circuit, and maintains a unique advantage in the short-range detection of the target's movement and intelligent control.
