Our take on the Human Presence Sensor 24G MmWave Human Detector

A ZigBee 3.0 presence sensor built on 24 GHz millimeter-wave radar. Unlike passive infrared sensors that only catch motion, it reports both moving and still people, including small movements like breathing, across a 120-degree field. It mounts on a ceiling or wall and runs from a 5V USB-C supply. It suits people automating lighting or security who want lights and alerts to respond to someone sitting still, not just walking through.

Pros
  • Detects stationary people, not just motion
  • 24 GHz radar picks up small movements like breathing
  • 120-degree detection angle covers a wide area
  • Ceiling or wall mounting
  • Standard ZigBee 3.0 pairing with a hub
  • USB-C powered
Cons
  • Needs a ZigBee hub and a 5V USB-C power source
  • Radar can trigger through thin walls or partitions
  • No battery option, so placement depends on a cable
  • Setup and sensitivity tuning take some trial and error

About the Human Presence Sensor 24G MmWave Human Detector

This human presence sensor uses 24G millimeter wave to detect both human movement and people who are standing still. It can pick up very small movements, including breathing and heartbeat.

It connects over ZigBee 3.0 and can be used for lighting, security and home appliance control. It can also be used in hotels, garages, buildings, transportation and other IoT applications that need motion detection and a set detection distance. Because it senses people who are not moving, it can turn a kitchen light on when you enter the room and off when you leave.

The sensor can be mounted on a ceiling or a wall. It can be used to detect intruders in a home, office, retail space or industrial setting.

Questions and answers

How is this different from a PIR motion sensor?
PIR sensors react to moving heat and drop out when a person stops. This radar sensor keeps reporting presence while someone is still, which is what keeps lights on in an occupied room.
Do I need a hub to use it?
Yes. It talks ZigBee 3.0, so it needs a compatible ZigBee hub or gateway to connect to your smart home system.
Can it be powered by battery?
No. It runs on 5V through USB-C at up to 70mA, so it needs a nearby outlet or USB supply.
Where should I mount it?
It works on a ceiling or wall with a 120-degree detection angle. Keep it away from thin partitions and moving fans or curtains that radar may pick up.
Will it detect someone sitting still?
Yes. It is designed to sense static presence and small movements such as breathing, not only walking.
What is in the box?
The sensor itself. A USB-C power supply and cable are not included.
Where is the Human Presence Sensor 24G MmWave Human Detector cheapest?
At Walmart, for $31.16, as of our latest check.
