The SEN0395 is a 24GHz millimeter-wave radar module that detects people whether they are still or moving, including someone sitting or sleeping. It covers a 100° horizontal field up to 9 meters, and unlike PIR or ultrasonic sensors it is largely unaffected by temperature, light or ambient noise. It is the sensor used in the Everything Presence One kit and is plug and play with the Everything Presence Lite. It suits smart-home tinkerers building room-level presence automation, not plug-in consumer devices.

Owners of the Everything Presence boards rate the SEN0395 for holding presence while someone sits still, which PIR sensors fail at. Complaints center on false triggers through walls and the tuning needed to calm it.
The SEN0395 is a 24GHz millimeter-wave presence sensor for human presence detection, environmental monitoring and real-time monitoring projects. It detects presence at up to 9 meters, with a horizontal detection range of 100°.
Unlike infrared and ultrasonic presence sensors, it can detect both static and moving objects. It is also less affected by temperature changes, changes in ambient light and environmental noise.
It is the sensor that ships with the original Everything Presence One. It is plug and play with the Everything Presence Lite.
