The C4001 presence sensor uses microwave signals with a frequency of 24GHz. It has a detection range of 100° horizontally, with a presence detection range of 16 meters and a motion detection and distance measurement range of 25 meters. It is suitable for detecting human presence, environmental monitoring, and real-time monitoring projects.

The C4001 has the advantage of detecting both static and moving objects, offering strong resistance to interference. It can detect the presence of a person regardless of their state (sitting, sleeping, or in motion).

The sensor uses FMCW technology for distance and speed measurement, with a maximum measurement range of 25 meters and a speed measurement range from 0.1 to 10 meters per second. This technology allows for continuous distance measurement and updates on target motion.

The microwave technology is non-contact and is used to detect objects, providing information about their distance, speed, and angle.

Main features:

• Person detection: Detection range up to 16 meters and motion detection up to 25 meters.
• Distance measurement: Range from 1.2 meters to 25 meters.
• Speed detection: Range from 0.1 meters per second to 10 meters per second.
