ZigBee Smart Human Presence Sensor with mmWave Radar Detection Key Features and Benefits: Accurate Human Presence Detection: Detects human presence, static states, micromotion, and movement within a defined area using advanced mmWave radar technology. Capable of identifying even subtle movements, such as someone sleeping, for precise monitoring. Light Intensity Monitoring for Automation: Builtin illuminance sensor works with the Tuya Smart App to trigger smart scene linkages with other devices. Automatically turn lights on or off based on ambient brightness. Easily integrate with other smart home systems for seamless automation. Adjustable Sensitivity and Range: Sensitivity levels adjustable from 1 to 9 to suit individual preferences. Detection range is configurable from 0.00m up to 9.5m, providing flexibility for different spaces and usage needs. Delay Settings: Set unmanned delay time between 5 and 1500 seconds and detection delay from 0.1 to 10 seconds to minimize false alarms and avoid unwanted triggers from irrelevant movement. ZigBee Hub Compatibility: Requires a Tuya ZigBee gateway for operation. The gateway acts as a bridge for all Tuya ZigBee devices, ensuring stable connectivity and higher compatibility compared to other hubs. Recommended for wholehouse smart integration. Data Reporting Control in ZigBee2mqtt: feature allows you to set the data reporting interval to reduce unnecessary network traffic. Realtime updates are maintained when presence status changes, ensuring accurate monitoring without excessive data transmission. Simple Integration with ZigBee2mqtt: If your ZigBee2mqtt system cannot detect the device automatically, user can request JS files from support or download them via GitHub by searching 'wzwenzhi.' Compact WallMount Design: Small and lightweight for unobtrusive installation on walls or other suitable surfaces. Powered by USB TypeC 5V, making it easy to set up and relocate as needed. Performance Radar Module: Equipped with a 5.8G radar sensor offering strong antiinterference capability and accuracy human presence recognition for reliable performance in varied environments. Use Scenarios: 1. Bedroom Monitoring: Detect when someone is sleeping or present without triggering false alerts, enabling smart lighting that dims automatically during rest. 2. Office Space Management: Integrate with lighting to automatically power down when no one is detected, saving energy while maintaining comfort. 3. Entryway Surveillance: Trigger lights or security alerts only when human presence is confirmed, preventing activation from pets or irrelevant movement.
