Tuya Smart Human Presence Sensor | WiFi Micro-Motion & Breathing Detector, Infrared Radar + Light Sensor

The DROSS Tuya Smart Human Presence Sensor uses infrared radar (mmWave) technology to detect human presence, breathing and micro-motion — far more accurate than traditional PIR sensors. Pair it with smart lights, fans or switches for fully automatic, presence-based control of your home.

• Works with Tuya Smart and Smart Life apps (WiFi, no hub required)
• Detects presence, micro-motion and breathing via infrared radar — not fooled by stillness like PIR sensors
• Detection range: 0–8m, 120° x 120° coverage
• Built-in light sensor for lux-based automation (e.g. only turn on lights after dark)
• Available in two mounting types:
  • Wall Mounted (Model PST-ZY-M100-S) — USB 5V 1A powered
  • Ceiling Mounted (Model PST-ZY-M100-L) — AC 80–250V powered
• Create automations: turn on lights/fans automatically when someone enters a room, turn off when the room is empty
