TUYA Smart Human Presence Detector, Wi-Fi A wireless human presence detector that can be connected and configured directly through the Tuya Smart or Smart Life app. No additional hubs or gateways are required – all you need is a 2.4GHz Wi-Fi network and an Android or iOS smart device. The sensor reliably detects human presence even when a person remains still, making it ideal for smart lighting, heating, ventilation, and security systems. Extremely convenient and easy to use.  Features: The sensor uses advanced millimeter-wave (mmWave) radar technology which, unlike conventional PIR motion sensors, can detect not only movement but also human presence within a room. It can detect even very subtle body movements and breathing-related chest movements, allowing it to reliably identify human presence when a person is sitting, working at a computer, reading, or sleeping almost motionless. The sensor continuously monitors its surroundings and sends presence information to the Tuya Smart or Smart Life app whenever a person is detected. The app allows you to adjust human presence detection sensitivity, detection distance, presence delay time, and create various smart home automation scenarios. The collected data can be used in smart home systems to automatically control lighting, heating, ventilation, and other devices when a person enters or leaves a room. The radar signal can penetrate glass walls and partitions. No additional hubs or gateways are required. The sensor connects directly to a 2.4GHz Wi-Fi network, while Bluetooth (BLE) is used for faster initial pairing and configuration. Thanks to its ability to accurately detect human presence even without active movement, this sensor is ideal for smart lighting, heating, ventilation, and security applications. The sensor comes with a power cable and a mounting kit consisting of an adjustable bracket and adhesive mounting tape. Note: USB power adapter is not included and must be purchased separately.
