DFRobot mmWave - C4001 24GHz Human Presence Detection Sensor Long Range 25-Meter Human Detection Sensor With UART Interface For IoT & Automation

Description:

The DFRobot C4001 employs 24GHz millimeter-wave technology for highly accurate human presence and motion detection. Its broad 100° horizontal sensing angle delivers wide-area coverage. This sensor distinguishes between static presence (up to 16 meters) and dynamic motion with distance measurement (up to 25 meters).

Its precision makes it suitable for applications requiring reliable occupancy data, such as energy management, security alerts, and environmental control. The C4001 provides a robust solution for real-time monitoring and data collection.
