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.
The MC420S-1 (microwave motion detection module) is an X-band microwave sensor that uses Doppler phenomena to detect the movement. The resonant stability of the resonant FET oscillator of circuit provides all-weather stable performance under CW mode or low load pulsed-cycle environment. The balanced mixer enhances the sensitivity and reliability, widely used in anti-theft, dual technology detector, automatic sensor door, intelligent control, and medical and other fields.
