Problem & Solution

Traditional PIR motion sensors are notorious for turning lights off while you’re sitting still reading or working. There is nothing more frustrating than waving your arms frantically just to get the lights to turn back on because your sensor didn't detect your presence.

This Zigbee 24G mmWave Radar sensor solves this by detecting micro-movements—even your breathing. It distinguishes between a vacant room and a stationary person, ensuring your smart home automations are reliable, seamless, and truly intelligent without the annoyance of 'ghost' triggers.

Who Is It For?

This device is perfect for smart home enthusiasts, DIYers, and home automation hobbyists who use platforms like Home Assistant (via Zigbee2MQTT), Tuya, or SmartThings. It is specifically designed for those who want professional-grade presence detection without the high price tag of premium brands.

It is also ideal for budget-conscious users looking to upgrade their home security or energy-saving lighting systems, as it offers sophisticated radar technology at an incredibly accessible price point.

Key Features

  • 24GHz mmWave Radar Technology
    Detects even the slightest human presence, including breathing and heartbeat.

FAQ

Does this work without a Zigbee hub?

No, you need a Zigbee gateway (Tuya, ZHA, or Zigbee2MQTT) to connect this sensor to your network.

Can it detect if I am just sitting on the couch?

Final Verdict

While it requires a bit of configuration to tune the sensitivity, the ability to detect static presence is a game-changer that makes your home feel truly automated. It is the most cost-effective way to transition from basic motion triggers to genuine human presence detection.
