24G mmWave Human Presence Sensor – Zigbee/WiFi Smart Radar Motion Detector for Static & Micro-Motion – 4-6m Detection, 0-4000Lux Light Sensor, Tuya/Smart Life APP, Alexa & Google Compatible

Upgrade your smart home with true presence detection. The IHSENO 24G mmWave Human Presence Sensor uses advanced radar technology to detect not just walking people, but also stationary individuals, micro-movements, and even breathing. Unlike traditional PIR sensors that turn off lights when you sit still, this radar sensor keeps your smart home aware of your presence, ensuring your lights and devices stay on as long as you are in the room.

1. High-Precision 24G Radar Detection:
Powered by a 24GHz mmWave radar, this sensor provides stable and sensitive detection over a 4-6 meter range. It accurately identifies human motion, static presence (like sitting or sleeping), and micro-movements (like typing or blinking). It also features beam detection to precisely target specific areas while ignoring outside interference.

2. Customizable Radar Parameters via APP:
Take full control of your automation through the Tuya Smart or Smart Life app. You can quickly adjust the detection distance, sensitivity for both micro and macro motions, and the "presence keep time" (cooling time). This allows you to fine-tune the sensor to eliminate false triggers caused by swinging curtains, small pets, or moving fans.

3. 0-4000Lux Light Detection & Smart Linkage:
Equipped with a built-in illuminance sensor (0-4000Lux), it can trigger smart scenes based on ambient light. For example, you can set it to turn on the bathroom light only when someone enters AND the room is dark. It works seamlessly with smart switches: automatically turning lights ON when presence is detected and OFF when the room is empty. (Note: The lux value is for scene linkage reference, not professional-grade measurement).

4. Real-Time Push Alerts & Family Sharing:
Receive instant notifications on your smartphone whenever human movement is detected, making it an excellent addition to your home security. The app supports a "Device Sharing" function, allowing you to share access with family members so everyone can monitor and control the smart home together.

5. Two Connection Options (WiFi vs. Zigbee):

WiFi Version: Connects directly to your 2.4GHz Wi-Fi router. No hub required.

Zigbee Version: Requires a Tuya Zigbee Gateway (sold separately) for a more stable connection and lower power consumption.

6. Important Usage & Installation Notes:

Wired Power Supply: This device requires a continuous 5V power supply via a Type-C cable (cable included, plug not included).

Cooling Time: The sensor has a default 30-second (up to 1 minute) cooling time. It will show "someone" until this time passes.

Avoid Interference: Do not install two sensors facing each other. Stay away from moving objects (curtains, fans) during setup. If the sensor constantly shows "someone," try lowering the sensitivity or relocating the device.

Setup Tip: After installation, stay away from the device for at least 1 minute to allow it to calibrate to an "unmanned" state.
