The Xethru X4M300 presence sensor is the first to integrate Novelda’s X4 ultra wide band radar chip. Ultra sensitive and with excellent signal to noise performance, the sensor detects even the smallest human movement in a room.
What’s more, the sensor’s presence detection zone is fully programmable, and can be configured up to a distance of 9.4 metres. The sensor also accurately measures the distance to occupants.
The sensor provides developers with a complete occupancy or vacancy detection solution and is ready for deployment in a variety of commercial product applications including security, lighting and HVAC control.

The X4M300 presence sensor detects human presence by detecting all major and minor movements in a room. This might be a person walking into an office, or it might be the slightest hand movement of a person sat at a desk.
The sensor’s extreme sensitivity enables it to detect presence up to a distance of 9.4 meters with millimeter accuracy. It is also able to measure the distance between the sensor and the occupant and is not susceptible to ‘blind spots’ within the detection zone.
The X4 radar chip’s signal processing parameters are configured by default to respond to presence within a 1.5 - 3.5 second time frame. This short response time makes the sensor ideal for lighting control, where for reasons of safety, human presence needs immediate detection.
The X4M300 occupancy sensor does not depend on having an unobstructed view to the occupant and can easily see through light materials. Detecting the presence of a sleeping person covered with a blanket is no challenge for the sensor – it’ll sense the movement of a breathing chest.
While the majority of existing occupancy sensor technologies fail to detect stationary occupants, and suffer from high rates of false tripping, the X4M300 presence sensor is sensitive enough to detect presence from the slightest human movement, even a breathing chest.
