User manual for the Jieyue JY300-xx-WiFi human presence sensor covering installation, network setup, and parameter configuration.
The JY300-xx-WiFi human presence sensor uses a 24 GHz FMCW/CW millimeter‑wave module to detect micro‑movements such as breathing, allowing it to determine whether a person is present, moving, or stationary. The manual explains the detection principle, installation options, and how to configure the sensor via the Tuya Smart app.
Installation can be performed as a ceiling‑mount or with a universal bracket, with detailed wiring and power requirements (5 V ≥ 1 A). Network setup steps, app pairing, and parameter adjustments—including sensitivity, detection distance, and delay—are described, along with LED and buzzer status indicators and safety precautions. This manual is written in Chinese.
