Zigbee Human Presence Detector Smart Human Body PIR Sensor Radar Detector

About this deal

This is a Zigbee-connected smart sensor that combines passive infrared (PIR) and millimetre-wave radar detection to monitor human presence in a room. It combines traditional PIR sensing with radar-based detection, allowing it to identify both movement and continued presence. PIR sensing detects initial motion events, while radar monitoring maintains presence detection once a person stops moving -- helping to avoid common automation issues such as lights turning off while someone is seated or working at a desk. It is well suited to smart lighting, security, and home automation routines. It can detect not only moving people but also stationary ones, enabling seamless background features such as a kitchen light turning on when you enter and off once you leave. A Zigbee hub or gateway is required to use the sensor, acting as the central bridge for communication with other smart home devices. Many variants in this category also support platforms such as Home Assistant and Zigbee2MQTT, making them a popular choice for enthusiasts building custom smart home setups.
